This change allows Sandbox2 to change how the default FD for comms is chosen.

This is to abstract the FD number away, so that we can change the way the FD number is chosen/communicated.

We have removed an internal-only sandbox mechanism that has been deprecated
for years. Some formatting/include changes may leak into the OSS version.

This is the first in a series of changes that will remove our custom logging
implementation in favor of the newly released Abseil log library.

When not requesting any particular function, `sapi_library()` will try and
make available _all_ functions it finds. In this case, system headers should
be skipped to avoid inflating the API surface. Standard library functions
can still be manually requested by adding them to the `functions` (Bazel)/
`FUNCTIONS` (CMake) argument.

If it isn't, assume that the process has exited and the event msg contains an exit code.

Instead of doing waitpid() and processing one thread at a time, gather all waiting threads and then process them.
This avoids starving older threads when newer threads raise a lot of events.

This finally prevents Ninja from rebuilding everything needlessly each time a
CMake reconfiguration was triggered. The root cause is that we used
`file(WRITE ...)`, which always unconditionally overwrites, so Ninja sees
those files as "dirty".

E.g. a failed `KillSandboxee` for a timeout would already set the exit status code while there could be an external kill pending at the same time which would try to `KillSandboxee` again and thus set exit status code again.

This should make multithreaded sandboxees that exec (or send `SIGKILL`) behave more reliably.

Instead of calling `google::InitGoogleLogging()` directly, introduce an
indirection via a new utility library. After this change, Sandboxed API
should consistently use `sapi::InitLogging()` everywhere.
For now, `sapi::InitLogging()` simply calls its glog equivalent. However,
this enables us to migrate away from the gflags dependency and use Abseil
flags. Once a follow-up change lands, `sapi::InitLogging()` will instead
initialize the google logging library with flags defined from Aseil.
Later still, once Abseil releases logging, we can then drop the glog
dependency entirely.

Also revert the `.bazelversion` file again, as this will enforce a fixed
version, not a minimum version, which does not work well with our BazelCI.

Internally, we rely on clang-tidy to warn about using deprecated declarations.
And for using deprecated declarations within SAPI itself, we should not warn.
Drive-by:
- Fix warning in `mounts_test.cc`

`BUILD_TESTING` is a CMake provided option and we should use similar naming,
just like how Abseil does it.
- `SAPI_ENABLE_TESTS` -> `SAPI_BUILD_TESTING`
- `SAPI_ENABLE_CONTRIB_TESTS` -> `SAPI_CONTRIB_BUILD_TESTING`
- `SAPI_ENABLE_EXAMPLES` -> `SAPI_BUILD_EXAMPLES`
Drive-by:
- Fix option name in GitHub action

Including the `CTest` modules ensures that the `BUILD_TESTING` option is
defined and automatically calls `enable_testing()` if needed. It does not
change the default or introduce any dependencies on its own.
This follows what Abseil already does in their top-level `CMakeLists.txt`.

Bazel's `Runfiles::Create()` does not actually need a value for `argv0` in
order to find runfiles for the current `cc_binary`.
- Rename `runfiles.cc` to `runfiles_nobazel.cc`

This makes `sapi_library()` more compatible with Bazel's native `cc_library()`
rule.
