n2 (a reimplemntation of ninja) adds a check that depfiles only add
dependencies on source files, not generated files, because generated
files are not guaranteed to exist before an action runs if there isn't
an explicit dependency between the two.
This is the case for our glob result files. However, we can rework the
build so that they're directly depended on instead of using a depfile.

This involves some minor changes to testing infrastructure.
This is a rollforward of aosp/2628496 with a couple of minor changes:
- In ParseBuildFiles, filter out all build files that are kept due
to ShouldKeepExistingBuildFileForDir
- Add some minor test infrastructure for StubbedBuildDefinitions, with a
couple of proof of concept tests used to demonstrate its usage. This
pattern will become immensely more common as we implement allowlist v2
(as we will need to update all tests which today simulate build
definitions that have missing deps)

The "bazel sandwich" is a mechanism for bazel to depend on make/soong
outputs. The name comes from the fact that bazel is now at the top
and bottom of the build graph. This is intended to allow us to work
on converting the partition builds to bazel while not all of the
dependencies of the partition have been converted.
It works by adding the bazel_sandwich_import_file rule, which emits a
dangling symlink that starts with bazel_sandwich:, and includes
information that the aquery handler in soong reads. The aquery handler
rewrites the symlink so that it points to a file generated by
make/soong, and adds a ninja dependency from the symlink to the file
it's targeting.
This allows us to depend on make-built files from bazel, but notably
it doesn't allow us to depend on analysis-time information from make.
This shouldn't be a problem for the partitions, but limits the use of
the bazel sandwich to similar, less complicated types of builds.

The parsed BUILD files will be scanned for obvious definitions of BUILD
targets which have Android.bp counterparts. In such cases, bp2build will
automatically omit conversion of these defined modules (to prevent
collisions). With this change, we no longer need one-off denylisting of
modules which have BUILD file definitions.
This has a 0.03s to 0.2s slowdown for bp2build with current state. This
impact is identical on a heavier test branch, as well. I also ran an
experiment that applied BUILD scanning to all source BUILD files
(regardless of allowlisting), and this had a 2 second slowdown.
We may want to look into parallelizing or improving the performance of
this evaluation, but it's probably not worth the effort at this time,
since the current performance hit is small.
Test: New integration test

This allows USE_BAZEL_VERSION to be set for m builds, which will use
Bazelisk for any Bazel invocations during those builds.
This should be used only for manual debugging, typically to either test
new Bazel features, verify Bazel compatibility with Android, or culprit
find new Bazel breakages.
Test: Manually run builds with USE_BAZEL_VERSION, toggled off and on to
ensure the build was rerun. Tested with a broken commit, a working

Context
- from-text android.jar files are built using Metalava, and these can be
utilized in `decodeSdkDep` so that any modules that depends on APIs
can be compiled using from-text android.jars
- This change removes dependency on source java files when compiling
stub android.jar files

- Modify java_api_library module to create system modules using the
generated android.jar
- Replace modules in decodeSdkDep to link against java_api_library

Previously, symlink forest generation involved removing the entire
symlink forest and recreating it from scratch. With this change,
a) symlinks which need not change are untouched,
b) symlinks pointing to the wrong location are fixed, and
c) symlinks which should no longer exist are removed.
On AOSP on my local machine, this reduces the symlink forest generation
step from 2.5s to 1.1s clean, and 0.6s when a single file is added to
a source directory.
Bug: 257528847
