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.

The Plan part is missing, because it needs support from FromIr. That'll come in a follow up commit.
**Next PR**: #2529
This is the result of splitting up the mega PR into more digestible chunks. This is the smallest subset I've been able to collect. Missing parts are noted in comments.
The code isn't reachable from Main, so it won't affect the test suite. It just gets compiled for now.
For context, this splits up work from https://github.com/hasura/graphql-engine-mono/pull/2332
