Earlier, if the `select` root field had a custom root field set, the same custom root field was then used for the streaming subscription root field as well. This leads to duplicate root fields being generated in the `subscription_root`.
This PR fixes that. It provides a way to customize the streaming subscription root field and not use the `select` root field's custom root field name for the streaming subscription root field.

This reduces the usage of "utils" modules in the parsers code, especially those that are simply re-exported from elsewhere, to facilitate extracting the parsers code into its own library.
It mostly inlines the imports that are re-exported from `Hasura.Prelude` and `Data.Parser.JSONPath`. It also removes references to `Data.*.Extended` modules. When necessary, it re-implements the functionality (which is typically trivial).
It does not tackle all external dependencies. I observed the following that will take more work:
- `Data.GADT.Compare.Extended`
- `Data.Text.Extended`
- `Hasura.Base.Error`
- `Hasura.RQL.Types.Common`
- `Hasura.Server.Utils`

We have a lot of `assert st_code == 200` scattered about. This is a
problem because (a) it makes the code harder to parse and (b) the error
message is lacking; I have seen a few flaky tests which were impossible
to diagnose because I didn't know what the response _should_ be.
This reduces the number of places in which we perform this assertion
(moving most of them to `HGECtx.execute_query`), so that we can have a
better chance of seeing a useful error message on test failure.

This makes it easier to run the tests when `cd`-ing into the directory,
and also takes care of cleaning up the environment when you exit the
directory.
It also helps editors with direnv support find the relevant libraries
so that they can perform more helpful analysis.

This improves `parseJSONPath` and `encodeJSONPath` to encode special characters appropriately by delegating to Aeson.
This also makes a couple of improvements to `encodeJSONPath`.
1. The function is moved from `Hasura.Base.Error` to `Data.Parser.JSONPath`. This still doesn't seem too appropriate but it is somewhat better. I am basing this on the fact that its test cases already lived in `Data.Parser.JSONPathSpec`.
2. It now returns `Text`, not `String`.
4. It quotes strings with double quotes (`"`) rather than single quotes (`'`), just like JSON.

I found a couple of flaws in `TestNamingConventions` and friends:
1. We had two test cases with the same name, which means one of them
would be overwritten. Renamed to avoid conflict.
2. The `skipif` check for
`TestNamingConventionWithoutExperimentalFeature` seemed broken. I
have fixed it by making it line up with its `reason`, and extracted
some logic out into a function to avoid duplication.

### Description
The path to the metadata file in this test was given in a relative fashion, which therefore assumes that the tests are run from a specific folder. This PR relaxes this requirement by making use of `makeRelativeToProject`.

This reflects the two different usages, which should not be conflated.
We also propagate the type a little more, to avoid `Text`.

We only use these `Show` instances in error messages (where we call
`show` explicitly anyway) and test cases (in which Hspec requires `Show
a` for any `a` in an assertion).
This removes the instance in favor of a custom `showQErr` function
(which serializes the error to JSON). It is then used in certain error
message production which previously called `show` on a `QErr`.
There are two places where we serialize a QErr and then construct a new
QErr from the resulting string. Instead, we modify the existing QErr to
add extra information.
An orphan `Show QErr` instance is retained for tests so that we can have
nice test failure messages.
This is preparation for future changes in which the error message within
`QErr` will not be exposed directly, and therefore will not have a
`Show` instance. That said, it feels like a sensible kind of cleanup
anyway.

The definition of the Parse monad (which implements MonadParse) can be simplified from using two monad transformers to a single monad. We can simplify from:
```haskell
newtype Parse a = Parse
{ unParse :: ReaderT JSONPath (Except ParseError) a }
```
to
```haskell
newtype Parse a = Parse
{ unParse :: Except ParseError a }
```
In other words, we don't actually need a Reader monad at all.
The technique is that rather than _always_ keeping track of the `JSONPath` while traversing the query, instead simply wait until an error occurs, and if it does, we adjust its `JSONPath` while we're unrolling the stack, using `withExceptT`.

### Description
This PR rewrites OpenAPI to be more idiomatic. Some noteworthy changes:
- we accumulate all required information during the Analyze phase, to avoid having to do a single lookup in the schema cache during the OpenAPI generation phase (we now only need the schema cache as input to run the analysis)
- we no longer build intermediary endpoint information and aggregate it, we directly build the the `PathItem` for each endpoint; additionally, that means we no longer have to assume that different methods have the same metadata
- we no longer have to first declare types, then craft references: we do everything in one step
- we now properly deal with nullability by treating "typeName" and "typeName!" as different
- we add a bunch of additional fields in the generated "schema", such as title
- we do now support enum values in both input and output positions
- checking whether the request body is required is now performed on the fly rather than by introspecting the generated schema
- the methods in the file are sorted by topic
### Controversial point
However, this PR creates some additional complexity, that we might not want to keep. The main complexity is _knot-tying_: to avoid lookups when generating the OpenAPI, it builds an actual graph of input types, which means that we need something similar to (but simpler than) `MonadSchema`, to avoid infinite recursions when analyzing the input types of a query. To do this, this PR introduces `CircularT`, a lesser `SchemaT` that aims at avoiding ever having to reinvent this particular wheel ever again.
### Remaining work
- [x] fix existing tests (they are all failing due to some of the schema changes)
- [ ] add tests to cover the new features:
- [x] tests for `CircularT`
- [ ] tests for enums in output schemas
- [x] extract / document `CircularT` if we wish to keep it
- [x] add more comments to `OpenAPI`
- [x] have a second look at `buildVariableSchema`
- [x] fix all missing diagnostics in `Analyze`
- [x] add a Changelog entry?
