Both 'schedule' and 'workflow_dispatch' are valid alternatives today. What we really want here is anything *except* pull request events.

These will still use MSVC as the compiler, but will no longer generate Visual Studio projects for the builds. Visual Studio is particularly bad at parallelizing builds, and is hostile to ccache.
This change also tweaks the ccache setup to prevent unbounded the growth observed in our github caches. Windows builds have had debug symbols stripped to reduce ccache size by a factor of 2x, and ccache maximum have been tweaked so that we persist fewer older builds.
Before this change, each CMake build took 12 minutes on every run (plus some constant overhead from staleness/gcloud), even with caching or on large multi-core runners. No amount of caching or parallelization made any noticeable difference above noise. With this change, we see the following improvements:
- 12 minutes to build from scratch on normal runners (unchanged)
- 4 minutes on 32-core runners from scratch
- 1 minute with optimal caches available on normal runners.
- 30 seconds on 32-core runners with optimal caches

Use the bash GHA to ensure WKTs are current, and then just directly invoke
Xcode. This means the script full_mac_build.sh can go back to just being
a simpler helper for folks doing local builds and we can remove all the extra
support that was needed for CI.

Changes to these files *can't* be tested in forked PRs, so we should explicitly block them with an error message to explain why.

objc_library really will only build for Apple platforms, so tag it as such.
The objc conformance test really will only build/run on macOS, so tag it as
such.
With these two changes, it should be safer for recursive builds that include
this directory no matter what the host platform is.

Since the sources can't reference each other, this is what helps keep them in
sync. Move it out to be a stand alone test in bazel instead of having it wired
into the Xcode projects.

This change introduces a dedicated StringBlock class that hosts block allocated string instances which are destroyed when the arena gets destroyed.
Experiments have shown this to save 0.40% in memory and 0.10% of CPU in arena heavy use cases.

- General naming up to "Objective-C" that some linters want, so just
use it every where for consistence.
- Add a bazel macOS config
- Includes the conformance test, so drop it from the Xcode flows.
- Tweak the naming on the Xcode flows so they are a little more clear.
- CocoaPods flows:
- Give them (hopefully) clear naming
- Use the same `image` as the Xcode tests
- Pin the Xcode version to match the Xcode tests

This should substantially reduce network flakes, since most builds will no longer need to download external dependencies. Because these caches actually get pretty expensive (~300 MB just from 1 openjdk dependency), we've taken some precautions:
1) The caches only get updated on push events (i.e. post-submit jobs)
2) Only a single job will push a new cache for any os/branch/commit combination. This will be whichever job finishes its bazel run first, and *also* has updates for the cache. Over time, the cache should expand to the full set of transitive dependencies as the quicker jobs stop pushing updates.
3) A clear_caches workflow has been introduced to reset the caches in case they grow too large. This will run monthly for now, but can also be run manually.

This CL also includes some cleanups to the core FieldVars function, and eliminates what had long-since become vestigial functions for setting variables. This needs to be part of the same CL because those functions used string_view-keyed maps.

It isn't worth the effort to try and compute the correct minimal set for each
sub file, and the more Swift folks use on top of this, the less it matters
as the modules will need everything anyways.

This code is experimental and should not be expected to emit working code, and callers are liable to break without warning.
It is being released now so that development can occur in the open, but users should not expect this to be supported any time soon.
