### 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

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.

This PR simplifies the types that represent a remote relationship in IR so that they can be reused in other parts (in remote schema types) which could have remote relationships.
The comments on the PR explain the main changes.

While it looks like a lot of work in FromIr.hs, you can rather review the type changes in `Hasura.Backends.MySQL.Types.Internal` and the changes to FromIr are only to reflect that. Essentially we're simplifying the FromIr code to not think about SQL-based joins: instead, FromIr produces fields necessary for the dataloader Plan/Execute to do their job properly.
I've done my best to ensure that all the hunks in the diff in this PR are minimal for slightly easier perusing.
I think future PRs will be more intentionally well structured, rather than created retroactively.

The tests have been run like this on my machine. I don't know more beyond that.

This is the next part in the series of MySQL PRs.
**Purpose**: Adds the Plan module for the data loader.
**Preceding PR:** #2511
**Next PR:** #2549
After #2511 is merged, this can be repointed to `main`. For now it's aimed at #2511, because then the diff display is simpler.
The `undefined` stubs in this PR have code already written, so they won't introduce a maintenance problem. They're only omitted for digestibility of the PR.

This commit applies ormolu to the whole Haskell code base by running `make format`.
For in-flight branches, simply merging changes from `main` will result in merge conflicts.
To avoid this, update your branch using the following instructions. Replace `<format-commit>`
by the hash of *this* commit.
$ git checkout my-feature-branch
$ git merge <format-commit>^ # and resolve conflicts normally
$ make format
$ git commit -a -m "reformat with ormolu"
$ git merge -s ours post-ormolu

## Description
Almost all our data structures use strictness annotations, following [our styleguide's principle](https://github.com/hasura/graphql-engine/blob/master/server/STYLE.md#dealing-with-laziness) of "by default, use strict data types and lazy functions". The very few cases where we actually need laziness were already explicitly labelled as lazy with the `~` prefix operator.
This PR simply globally enables `StrictData`, allowing us to express records without `!()` on every field, but makes no attempt at cleaning existing code.
