This will make PRs from forked repositories significantly less painful, since they'll agree on which version of each action to use. OTOH, we'll have a separate repo that needs to be maintained, and changes to it will need to be coordinated and versioned carefully. This will likely need to be done less often though now that our infrastructure is stable.

This uses ccache + github caching to substantially decrease the time it takes to run CMake builds. Due to Bazel caching, these are some of our slowest tests, causing one of the biggest presubmit bottlenecks

This migrates from reusable workflows to composite GHA actions. This has the following advantages:
1) We can split them into smaller, easier to reason about chunks
2) We can reuse them more freely between each other and workflows
3) They don't complicate the job names
4) In theory they'll be easier to test in isolation. While composite actions can't be unit-tested, we can easily break them up into nodejs or docker actions that can be.
As a proof of concept, some of our non-Bazel tests are migrated to GHA as well (CMake + Composer)
