Partially reverts #32686.
PR caches inherit from caches generated in `main`. If it cannot find
that cache, it will create one scoped to just that PR (and PRs that
inherit from it).
There is an edge case where cache eviction can happen in the middle of a
test run. If cache eviction removes a `main` cache, child jobs that
depend on it will start failing because of the `fail-on-cache-miss`
setting.
This PR reverts the default behavior. If this happens, the workflow will
still continue in slow mode where it will `yarn install` child jobs
instead of reusing from cache. This is slower but will at least allow
workflows to continue.
Additionally I added restore keys so that we can fallback to other
caches if present so `yarn install` doesn't need to start over from
scratch.
Since we use a centralized cache we should fail subsequent steps if the
child jobs are unable to restore the cache from the first 2 jobs.
Also fix some incorrect hashes used for the fixture tests.

Defaults to warn, but since some steps require these artifacts to be
uploaded we specify an error if its not found. Some other steps like
playwright test-results are only uploaded on failure so it's okay to
ignore.

To avoid race conditions where multiple jobs try to write to the same
cache, we now centralize saving the cache and then reusing it in every
subsequent job.

Follow-up to #31850. We want to build using the original commit SHA, not
the merge commit that GitHub Actions creates behind the scenes. We were
already checking out the correct commit object, but the COMMIT_SHA
artifact was still pointing to the merge commit.
This should fix the sizebot links to point to working URLs, too.
We only need the compiler built for `yarn test` in the root directory.
Rather than always cache both for every step, let's just do it where
it's needed explicitly.

Now that the compiler lint rule is merged into
eslint-plugin-react-hooks, we also need to update our caches so compiler
dependencies are also cached. This should fix the CI walltime regression
we are now seeing.

Randomly noticed this when I looked at a recent [DevTools regression
test run](https://github.com/facebook/react/actions/runs/13578385011).
I don't recall why we added `continue-on-error` previously, but I
believe it was to keep all jobs in the matrix running even if one were
to fail, in order to fully identify any failures from code changes like
build or test failures.
There is now a `fail-fast` option which does this.
[`continue-on-error`](https://docs.github.com/en/actions/writing-workflows/workflow-syntax-for-github-actions#jobsjob_idcontinue-on-error)
now means:
> Prevents a workflow run from failing when a job fails. Set to true to
allow a workflow run to pass when this job fails.
so it's not correct to use it.
There's no real reason to have 2 jobs for sizebot. It's more of a
historical artifact from before the GH migration. Merging them should
require one less worker needing to be provisioned and some of the extra
overhead

I just noticed that we don't actually need to let the devtools build
finish first because the e2e tests don't use those built files. We can
decouple them to allow them to run in paralllel.
Building DevTools is currently the long pole for the runtime CI job.
Let's see if we can get the overall runtime for runtime build and test
down by speeding this one step up.

The DOM fixture hasn't worked on local builds since the UMD support was
removed in https://github.com/facebook/react/pull/28735
Here we update the fixture to set the local experimental builds to
window. Some of the pages are still broken, such as hydration. But these
bugs exist on other versions as well and can be cleaned up separately.
This updates the CI workflow for the runtime build and tests to use the
HEAD commit of the PR branch rather than the Fake News merge commit that
the `@actions/checkout` action bafflingly defaults to.
Testing against the merge commit never made sense to me as a behavior
because as soon as someone updates upstream, it's out of date anyway.
It should just match the exact commit that the developer pushed, and the
once that appears in the GitHub UI.
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.
I happened to notice some jobs on main get canceled if another PR landed
before the prior commit on main had finished running CI. This is not
great for difftrain because the commit artifacts job relies on the CI
jobs on main finishing before it triggers. This would lead to commits
being skipped on DiffTrain which is not great for provenance since we
want it to be a 1:1 sync.

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.

The download job for sizebot requires both modules from the root repo
but also has a nested yarn lockfile in scripts/release. Calculate the
hash for the cache using both lockfiles.

Build artifacts are uniquely associated to a single workflow run, so
appending the sha was unnecessary. I originally included it to make it
easier to download later but this turns out to be unneeded.
Drops the sha suffix to make downloading the artifact in a separate
script / workflow more straightforward.

The tests for the build currently take about 3.5 minutes and is at the
moment the long pole for the whole workflow. By sharding we can make
this workflow faster and save about a minute or so in overall wall time.

Merges most workflows into a single workflow, which should make the
"Checks" tab easier to visualize sincee it will all be graphed in a
single interface. There should be no change in behavior, this is a
mechanical change.
