### Description
This PR is a first step in a series of cleanups of action relationships. This first step does not contain any behavioral change, and it simply reorganizes / prunes / rearranges / documents the code. Mainly:
- it divides some files in RQL.Types between metadata types, schema cache types, execution types;
- it renames some types for consistency;
- it minimizes exports and prunes unnecessary types;
- it moves some types in places where they make more sense;
- it replaces uses of `DMap BackendTag` with `BackendMap`.
Most of the "movement" within files re-organizes declarations in a "top-down" fashion, by moving all TH splices to the end of the file, which avoids order or declarations mattering.
### Optional list types
One main type change this PR makes is a replacement of variant list types in `CustomTypes.hs`; we had `Maybe [a]`, or sometimes `Maybe (NonEmpty a)`. This PR harmonizes all of them to `[a]`, as most of the code would use them as such, by doing `fromMaybe []` or `maybe [] toList`.

## Motivation
This PR rewrites most of Relay to achieve the following:
- ~~fix a bug in which the same node id could refer to two different tables in the schema~~
- remove one of the few remaining uses of the source cache in the schema building code
In doing so, it also:
- simplifies the `BackendSchema` class by removing `node` from it,
- makes it much easier for other backends to support Relay,
- documents, re-organizes, and clarifies the code.
## Description
This PR introduces a new `NodeId` version ~~, and adapts the Postgres code to always generate this V2 version~~. This new id contains the source name, in addition to the table name, in order to disambiguate similar table names across different sources (which is now possible with source customization). In doing so, it now explicitly handles that case for V1 node ids, and returns an explicit error message instead of running the risk of _silently returning the wrong information_.
Furthermore, it adapts `nodeField` to support multiple backends; most of the code was trivial to generalize, and as a result it lowers the cost of entry for other backends, that now only need to support `AFNodeId` in their translation layer.
Finally, it removes one more cycle in the schema building code, by using the same trick we used for remote relationships instead of using the memoization trick of #4576.
## Remaining work
- ~~[ ]write a Changelog entry~~
- ~~[x] adapt all tests that were asserting on an old node id~~
## Future work
This PR was adapted from its original form to avoid a breaking change: while it introduces a Node ID V2, we keep generating V1 IDs and the parser rejects V2 IDs. It will be easy to make the switch at a later data in a subsequent PR.

When running `npm run server-build`, this step will make sure that `npm
ci` is run first if necessary.
It will run whenever _package.json_ or _package-lock.json_ are changed.

## Description ✍️
- Creates a new `/capabilities` endpoint for the GDC agent API
- Removes capabilities from the `/schema` endpoint
- Removes the `/config-schema` endpoint and includes the `ConfigSchemaResponse` within the `CapabilitiesResponse`

This pulls the script to download the common assets out of the
`server-build` Makefile target into its own target. Because we use the
output directory name as the target, we allow `make` to decide whether
it's necessary.
As there are no inputs to the target, it will only be done once.
Behavior should be unaffected.

## Description
This PR adds a config file for [`weeder`](https://github.com/ocharles/weeder) to the `-mono` repository. `weeder` checks for dead code by building a call graph from the given entry points (currently every module named `Main` with a `main` function) and then marking every function _not_ in that call graph as dead code.
To avoid very large PRs, I'm going to tackle this in a series. This first PR adds the basic configuration, plus removes as many weeds as it took for me to realise this was going to become a very big PR. The PRs after this will largely be removing dead code, until the final PR that will add Weeder to the CI pipeline.

This is a first step towards clarifying the role of `UnpreparedValue` as part of the IR. It certainly does not belong in the parser framework.

### Description
This PR does several things:
- it cleans up some structural issues with the engineering documentation:
- it harmonizes the table of contents structure across different files
- adds a link to the bigquery documentation
- moves some files to a new `deep-dives` subfolder
- puts a title at the top of each page to avoid github assuming their title is "table of contents"
- it pre-fills the glossary with a long list of words that could use an entry (all empty for now)
- it adds the only remaining relevant server file from [hasura-internal's wiki](https://github.com/hasura/graphql-engine-internal/wiki): the old "multiple backends architecture" file
### Discussion
A few things worth discussing in the scope of this PR:
- is it worth migrating old documentation such as the multiple backends architecture, that document a decision process rather instead of being up-to-date reflections of the code? are we planning to delete hasura-internal?
- should we focus instead on _new_ documentation, aimed to be kept up to date?
- are there other old documents we want to move in here, or is that it?
- is this glossary structure ok, or would a purely alphabetical structure make sense?
- does it make sense to have the glossary only in the engineering section? more generally, _what's our broader plan for documentation_?
