Bug 1932322 - Implement the new collection-enabled API

[badboy]

This is the mega PR changing the inner workings of Glean to support collection-enabled and follows-collection-enabled on pings, to independently control a subset of pings and whether they can get submitted.

BREAKING CHANGE: This is definitely a huge breaking change.

2024-11-21: This is not yet fully ready for review

• Some docs (though I probably will split some out to followups)
• Fill in remaining TODOs
• Update a few commit messages
• File bugs where I think we should optimize things in followups
• Merge Bug 1932322 - Support follows_collection_enabled for pings glean_parser#776 (and release and update glean-parser)
• Ensure the tests test the right thing
• Ensure our tests cover a large enough part of the new API to be confident about it
• Changelog entry

Lot's of little cleanup things, nothing major. I'd say this fits really well with my mental model of what this would look like from our discussions.

Also, docs/changelog/etc. ofc
