Our CI workflows generally cache `**/node_modules` (note the glob, it
caches all transitive node_module directories) to speed up startup for
new jobs that don't change any dependencies. However it seems like one
of our caches got into a weird state (not sure how it happened) where
the `build` directory (used in various other scripts as the directory
for compiled React packages) would contain a `node_modules` directory as
well. This made sizebot size change messages very big since it would try
to compare every single file in `build/node_modules`.
The fix is to ensure we always clean the `build` directory before doing
anything with it. We can also delete that one problematic cache but this
PR is a little more resilient to other weird behavior with that
directory.
Adds tests for Compiler integration.
This includes:
- Tests against Compiler from source.
- Versioned (18.2 - <19) tests against Compiler from npm.
For tests against React 18.2, I had to download `react-compiler-runtime`
from npm and put it to `react/compiler-runtime.js`.
actions/cache has a default timeout of 10 minutes. Occasionally the
cache service download gets stuck and it waits this amount of time
before proceeding like it was a cache miss.
10 minutes is way too long so let's shorten this to a minute.

More or less a straight copy from the circleci config. I spotted some
inefficiencies but will fix those later to make reviewing this easier.

## Summary
This pull request converts the CircleCI workflows to GitHub actions
workflows. [Github Actions
Importer](https://github.com/github/gh-actions-importer) was used to
convert the workflows initially, then I edited them manually to correct
errors in translation.
**Issues**
1. facebook/react/devtools_regression_tests
The scripts that this workflow calls need to be modified.
