80243a5c34 Remove MonadTableInfo and MonadRole.
### Description

This PR moves Hasura-specific schema functions from `Hasura.GraphQL.Parser.Class` into `Hasura.GraphQL.Schema.Common`. It also removes the two corresponding monad aliases, and consequently harmonizes several parts of the code to use the same common constraint.

4ccc830bb8 Tidy up MSSQL.FromIr
## Description

We go through the module `Hasura.Backends.MSSQL.FromIr` and split it into separate self-contained units, which we document.

Note that this PR has a slightly opinionated follow-up PR #3909 .

### Related Issues

Fix #3666

### Solution and Design

The module `FromIr` has given rise to:

* `FromIr.Expression`
* `FromIr.Query`
* `FromIr.Delete`
* `FromIr.Insert`
* `FromIr.Update`
* `FromIr.SelectIntoTempTable`

And `Execute.MutationResponse` has become `FromIr.MutationResponse` (after some slight adaptation of types).

b9ee669ee1 Improve remote joins collect
### Description

This PR improves the `Collect` module by re-ordering the functions to make clear what is public API and what is internal implementation. Furthermore, it makes use of `traverseOf` and `traverseFields` to reduce duplication. To do so, it also introduces a few more lenses in the rest of the codebase, and uses this opportunity to harmonize some structures that were not following our naming convention.

While the diff is massive, a lot of it is just code moving around; the file is now divided into separate sections:
- entry points: IR types for which we want to run the collection
- internal monadic structure
- internal traversals: functions that do nothing but drill down further
- actual transformations: the three cases where we do actually have work to do: selection sets on which we do want to insert join columns, extract remote relationships... those functions are left unchanged by this PR
- internal helpers

b9ad721ea6 Reduce boolean blindness by promoting data type StringifyNumbers
I discovered and removed instances of Boolean Blindness about whether json numbers should be stringified or not.

Although quite far-reaching, this is a completely mechanical change and should have no observable impact outside the server code.

d50aae87a5 Updates cabal freeze file
#### TODO

- [x] fix `hashable >= 1.3.1` serialization ordering issue [^1]
  - `test_graphql_mutations.py::TestGraphQLMutateEnums` was failing
- [x] fix `unordered-containers` serialization ordering issue [^2]
  - `test_graphql_queries.py` was failing on Citus
- [ ] verify that no new failures have been introduced
- [ ] open issues to fix the above
  - identify test cases that "leak" implementation details by depending on `hashable` instance ordering
  - bump `hashable >= 1.3.1` and update test cases with new ordering OR modify them so that ordering is stable
  - bump `unordered-containers >= 0.2.15.0` and update test cases with new ordering OR modify them so that ordering is stable
    - one of the test cases was failing on string equality comparison for a generated Citus query
    - we probably don't want to _actually_ do this unless there are _very specific_ guarantees we want to make about generated query structure
---

Just what it says on the tin.

https://github.com/hasura/graphql-engine-mono/pull/3538 updated the freeze file a few weeks ago, but it looks like the index state hadn't been updated since December so a lot of stuff that had newer versions didn't get updated.

---

EDIT: I should add, the motivation for doing this in the first place is that `hspec > 2.8.4` now supports specifying filtering spec trees based on patterns provided by the `HSPEC_MATCH` environment variable.

For example, one could have a script that executes the following:
```
HSPEC_MATCH="PostgreSQL" \
  ghcid \
    --command \
      'cabal repl graphql-engine:test:tests-hspec \
         --repl-option -O0 \
         --repl-option -fobject-code' \
    --test "main"
```
...which will loop on typechecking the `tests-hspec` component, and then as soon as it passes (i.e. no warnings or errors) will run _only_ the `PostgreSQL` sub-components.

[^1]: `hashable >= 1.3.1.0` [updated its default salts](https://github.com/haskell-unordered-containers/hashable/pull/196), which [broke serialization ordering](https://github.com/haskell/aeson/issues/837)
[^2]: `unordered-containers >= 0.2.16.0` [introduced changes to some of its internal functions](https://hackage.haskell.org/package/unordered-containers-0.2.16.0/changelog) which seem like they could have affected serialization stability

f026d44438 Role-invariant schema constructors
We build the GraphQL schema by combining building blocks such as `tableSelectionSet` and `columnParser`. These building blocks individually build `{InputFields,Field,}Parser` objects. Those object specify the valid GraphQL schema.

Since the GraphQL schema is role-dependent, at some point we need to know what fragment of the GraphQL schema a specific role is allowed to access, and this is stored in `{Sel,Upd,Ins,Del}PermInfo` objects.

We have passed around these permission objects as function arguments to the schema building blocks since we first started dealing with permissions during the PDV refactor - see hasura/graphql-engine@5168b99e46 in hasura/graphql-engine#4111. This means that, for instance, `tableSelectionSet` has as its type:
```haskell
tableSelectionSet ::
  forall b r m n.
  MonadBuildSchema b r m n =>
  SourceName ->
  TableInfo b ->
  SelPermInfo b ->
  m (Parser 'Output n (AnnotatedFields b))
```

There are three reasons to change this.

1. We often pass a `Maybe (xPermInfo b)` instead of a proper `xPermInfo b`, and it's not clear what the intended semantics of this is. Some potential improvements on the data types involved are discussed in issue hasura/graphql-engine-mono#3125.
2. In most cases we also already pass a `TableInfo b`, and together with the `MonadRole` that is usually also in scope, this means that we could look up the required permissions regardless: so passing the permissions explicitly undermines the "single source of truth" principle. Breaking this principle also makes the code more difficult to read.
3. We are working towards role-based parsers (see hasura/graphql-engine-mono#2711), where the `{InputFields,Field,}Parser` objects are constructed in a role-invariant way, so that we have a single object that can be used for all roles. In particular, this means that the schema building blocks _need_ to be constructed in a role-invariant way. While this PR doesn't accomplish that, it does reduce the amount of role-specific arguments being passed, thus fixing hasura/graphql-engine-mono#3068.

Concretely, this PR simply drops the `xPermInfo b` argument from almost all schema building blocks. Instead these objects are looked up from the `TableInfo b` as-needed. The resulting code is considerably simpler and shorter.

One way to interpret this change is as follows. Before this PR, we figured out permissions at the top-level in `Hasura.GraphQL.Schema`, passing down the obtained `xPermInfo` objects as required. After this PR, we have a bottom-up approach where the schema building blocks themselves decide whether they want to be included for a particular role.

So this moves some permission logic out of `Hasura.GraphQL.Schema`, which is very complex.
