Add tests for coalesce and fix the In-memory version
# Important Notes
The distribution/lib/Standard/Database/0.0.0-dev/src/Internal/IR/From_Spec.enso change isn't actually needed for this MR as I switched away from using literal tables for these tests as trying to mix 2 literal tables doesn't look to be supported. The change I added will let any future developers know that.
- Trying to debug #11145, I'm adding logging of when token is refreshed and when that fails, with possibly some details that are included in the response.
- Also, the expired case is now narrowed down from 400-499 to just 401 as that's what [OAuth spec](https://www.rfc-editor.org/rfc/rfc6750.html#section-3.1) says is the correct status code for expired token. Other errors are reported as unexpected error, with more details.
- Allow Interrupted Exceptions to float out of the web requests.
- Use `Type_Error` rather than Any when catching auto scoping resolving.
- Rename `Java_Exception` to `JException`
- Added `to_display_text` for `S3_File` and `Enso_File`.
- Improved widget for `AWS_Credential` allowing use of Enso secrets.
- Adjust `S3.list_objects` to return `S3_File` objects, allowing easier drill down.
- Fix for merging inherited config with direct config in widgets.
- Add missing constant types to Date.Diff widget.

Before 3.46, the SQLite parser had a limited stack, which could overflow for certain complex queries.
CTE optimizations make some of our queries much smaller, but also a little bit more deeply nested, causing the parser stack to overflow. 3.46 removes this stack limitation.
Closes#10910.

This implements `DB_Column.with`, which uses `WITH ... AS` SQL clauses to remove duplicates in the generated SQL.
After a discussion with @radeusgd, we concluded that we will probably want a more complete CTE implementation, so this one is useful for now to deal with big queries (like `round`).
# Important Notes
Still to do in this PR:
- [x] Rename `with` to `let` (or something similar)
- [x] tests
- [x] documentation
- [x] remove `State` hack by moving query generation into a class and using a `Ref` field for scoping

- Closes#10411
- Also a similar technique allowed to add partial support for SQLite as well.
- Only `include_nothing=True` case is still not supported as the technique used for Snowflake did not port well to SQLite and I did not find yet a satisfactory workaround (it is doable, but too ugly to justify it for now IMHO).
- Review and update the doc comments of public functions in the AWS library.
- Reorder the functions to make the order in component browser (and online docs better).
- Align some error handling.
- Fix bug with `list` on root S3.
- Hide `S3.get_object` as it's single read makes it bad for GUI use.
- Enables the `..` autoscoping style for creating Atoms in expressions.
- Add type checking to methods in columns.
- Auto wrap returns from method in expressions into a column as needed.
- Remove `Time_Period.Day` to remove confusion..
- Closes#10716 by un-marking the `Snowflake_Connection` as `private`.
- Does the same to `SQLServer_Connection`.
- Makes sure that `Snowflake_Connection` has correct visualization and enables links for it.
- Adds a fallback in `to_default_visualization_data` and in Table's `prepare_visualization` so that if `to_js_object` of a given type is malformed, we still get some kind of visualization + debug info about the underlying error.
Majority of warnings handling is now done via newly introduced nodes. Moreover, the underlying representation of warnings storage in `WithWarnings` was changed from `Warning[]` to `EnsoHashMap`.
# Important Notes
- Remove `ArrayRope`.
- Adds `Hyper_File` allowing reading a Tableau hyper file.
- Can read the schema and table list.
- Can read the structure of a table.
- Can read data into an Enso Table.
Fixes#10609 by rewriting all our upload-related operations to rely on `DDL_Transaction` - an abstraction that handles 'transactionality' of `CREATE TABLE` statements dependent on if a given backend allows DDLs within transactions or not (if not it emulates transactionality by creating the tables outside of transaction and then dropping them on rollback).
- Close#10622
- Changes `project-manager` and `ensoup` launcher to run the engine/language-server with working directory set to the directory containing currently running project.
- If the working directory is _not_ "the directory containing currently running project", a warning is written to logs. This can happen if the raw `/bin/enso` engine runner is used in a different directory.
- In the Cloud, the `File.new` interprets relative paths as cloud paths relative to the Cloud directory containing the current project. Absolute paths are unaffected.
- Adjusted Filter_Condition removing keep/drop from basic filters.
- Fix Is_In to have selector.
- Fix for Date simple expressions.
- Add get_row to Table and DB_Table.
In a sequence of value-level operators, whitespace does not affect relative precedence. Functional operators still follow the space-precedence rules.
The "functional" operators are: `>> << |> |>> <| <<| : .`, application, and any operator containing `<-` or `->`. All other operators are considered value-level operators.
Asymmetric whitespace can still be used to form *operator sections* of value-level operators, e.g. `+2 * 3` is still equivalent to `x -> (x+2) * 3`.
Precedence of application is unchanged, so `f x+y` is still equivalent to `f (x + y)` and `f x+y * z` is still equivalent to `(f (x + y)) * z`.
Any attempt to use spacing to override value-level operator precedence will be caught by the new enso linter. Mixed spacing (for clarity) in value-operator expressions is allowed, as long as it is consistent with the precedences of the operators.
Closes#10366.
# Important Notes
Precedence warnings:
- The parser emits a warning if the whitespace in an expression is inconsistent with its effective precedence.
- A new enso linter can be run with `./run libraries lint`. It parses all `.enso` files in `distribution/lib` and `test`, and reports any errors or warnings. It can also be run on individual files: `cargo run --release --bin check_syntax -- file1 file2...` (the result may be easier to read than the `./run` output).
- The linter is also run as part of `./run lint`, so it is checked in CI.
Additional language change:
- The exponentiation operator (`^`) now has higher precedence than the multiplication class (`*`, `/`, `%`). This change did not affect any current enso files.
Library changes:
- The libraries have been updated. The new warnings were used to identify all affected code; the changes themselves have not been programmatically verified (in many cases their equivalence relies on the commutativity of string concatenation).
- Closes#9486
- All tests are succeeding or marked pending
- Created follow up tickets for things that still need to be addressed, including:
- Fixing upload / table update #10609
- Fixing `Count_Distinct` on Boolean columns #10611
- Running the tests on CI is not part of this PR - to be addressed separately
- Part of #9486
- Fixes `Table.union`, `merge` and `distinct` tests
- Replaces `distinct_on` in `Context` that was actually a Postgres specific addition leaking into the base with a more abstract `Context_Extension` mechanism.
- This allows us to implement the Snowflake-specific `DISTINCT` using `QUALIFY`.
- Related to #9486
- Batching of expression tests
- Fixing arithmetic by simplifying `%` and `/` operations
- Trying to share some more tables, sometimes improving performance sometimes not really
- Adding sorting and other fixes to tests to make them pass: Missing_Values_Spec, Filter_Spec, Map_Spec
- Fixing warnings related to materialization of Decimal->Integer, thus fixing Join_Spec.
- Related to #9486
- Ensures that even though an integer column in Snowflake is represented by `Decimal` type, if the values are small enough, they are materialized as `Integer`.
- If the values are larger, they are still read in as `Decimal`.
- Adds tests for some other `Decimal` edge cases (various precisions and scales), and for `Float`.
Fix#10503 by creating a benchmark and then speeding it up by making sure usage of `InteropLibrary` reminds in partially evaluated code and isn't hidden behind `@TruffleBoundary`.
- Related to #9486
- Fixes types in literal tables that are used throughout the tests
- Tries to makes testing faster by disabling some edge cases, trying batching some queries, re-using the main connection and trying to re-use tables more
- Implements date/time type mapping and operations for Snowflake
- Updates type mapping to correctly reflect what Snowflake does
- Disables warnings for Integer->Decimal coercion as that's too annoying and implicitly understood in Snowflake
- Allows to select a Decimal column with `..By_Type ..Integer` (only in Snowflake backend) because the Decimal column there is its 'de-facto' Integer column replacement.
- Removes `First` and `Last` from the `Standard.Base` exports.
- Enable auto-scoping for all `Index_Sub_Range` and `Text_Sub_Range`.
- Update all use of those methods to use auto-scoping.
- Remove publishing the constructors.
- Fix any missed use in libs.
- Alter tests to generally use auto-scoped calls.
- `on_incomparable` to `on_problems`.
