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.

This is a followup to aosp/2606989.
This flag is not necessary now that we're using one platform name
for all of mixed builds.
Also rename current_product to mixed_builds_product so that it's clear
that that this platform should only be used for mixed builds.
In addition, make the bazelrc files point to the named products again
instead of the mixed build product so that b builds will still have
qualified outputs, but mixed builds won't.

There are a number of instances where we are exporting information
from soong to bazel via soong_injection. This could be more bazel-centric
if the information was instead held in bzl files, and both bazel and
soong read it from there.
Add a starlark package that will run
//build/bazel/constants_exported_to_soong.bzl at initialization time,
and then results can be retreived with GetStarlarkValue.
Since changes to the starlark files mean that soong has to rerun,
add them as ninja deps.
Unfortunately, the starlark code has to be run at runtime rather than
pregenerating their results, because tests run from intellij wouldn't
go through any pregeneration steps. This means that starlark is run
multiple times during the build, once per test package and once per
primary builder invocation. (currently 3, could be reduced to 2 if we
made the symlink forest generation into its own standalone tool) The
starlark code we have so far in this cl is very fast, roughly half a
millisecond, so it's not a big deal for now, but something to keep an
eye on as we add more starlark constants.

With this CL, we avoid deleting the bp2build directory and regenerating
all BUILD files. Instead, we regenerate BUILD files which have changes
on the filesystem, and delete old BUILD files which should no longer
exist.
This improves incremental Bazel server performance by about ~5 seconds.
Previously, Bazel would have cache misses for regenerated packages, and
would thus need to analyze them even if no meaningful changes took
place.
For ease of implementation, we avoid removing stale (empty) directories
from the bp2build workspace, but this should have no effect on the
build. (These will be removed on next clean)

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.

Create a
build/bazel/product_config/generated/products/<product_name>/BUILD
file that contains the platform definitions needed for
a particular product. Currently we just create it for the
current lunch target, but the idea is that eventually when
all product config is in starlark, all the products will
have their platform definitions in the tree at once.

Users may disable bazel-by-default with BUILD_BROKEN_DISABLE_BAZEL, and

This required the following:
- Adding Platform_base_sdk_extension_version to default soong.variables
- Teaching the symlink tree creation code to understand symlinks
- Making finder.go follow symlinks when requested
Adding yet another knob is unfortunate, but I can't allow that
unconditionally because the Android code base contains a number of
symlinks giving rise to infinite directory trees because they point back
to their parent and this seemed preferable to adding complicated logic
like "follow symlink but if only its fully resolved version does not
point under the source tree".
I could be convinced about the latter, though.

It's better not to have state hidden in dotfiles (or rather,
dotdirectories) if we can help.
It's questionable whether the "linux-x86" path segment makes sense since
soong_build only ever runs on one operating system, but I didn't want to
rock the boat now.
Drive-by fixed some quoting fixes in rbc-run. Notably, I didn't wrap
`$@` into double quotes because I don't know whether the lack of double
quotes was intended or not.
Also drive-by fixed the fact that "out/soong" was added twice to the
directory name of bpglob. This turned out not to be a problem because
bpglob doesn't need to be explicitly built: if it's needed, it's
declared as an input of the glob files so it'll be built automatically
(at the cost of the first "null build" not actually being a null build)

This includes the JSON graph generator and bp2build.
Before:
GENERATE_BAZEL_FILES=1 m nothing
GENERATE_JSON_MODULE_GRAPH=1 m nothing
Now:
m json-module-graph
m bp2build
They can now also be combined with other targets or each other.
The longer-term goal is to run "m queryview" and "m soong_docs" using
the same infrastructure. There are two alternate approaches:
1. Call soong_build from within the main Ninja invocation. This requires
two sequential soong_build invocations and is thus slower.
2. Do everything requested in the same soong_build invocation. This
would be faster, but one AFAIU can't tell Ninja that multiple possible
actions can build the same output so that doesn't work.
(1) is somewhat more desirable because soong_docs seems to be built
from build/make/core/main.mk ; I assume that that can be worked around
although I haven't checked where the output of "m soong_docs" goes.

The following files are forked:
- build-globs.ninja
- The glob list files
- .d files for the glob list files
- The output file (build.ninja or the bp2build marker file)
This makes bp2build and soong_build not overwrite each other's files
they need for proper incrementality.

This fixes null bp2build builds.
When running bp2build, out/soong/.bootstrap/build-globs.ninja wasn't
generated, therefore none of the globs in out/soong/.primary/globs have
actions to generate them. This makes bp2build always re-run on a null
build, because it depends on those non-existent globs in its depfile.
Fix the above by generating a build-globs.ninja file with the globs that
bp2build encounters during conversion, and add tests to verify that null
builds and bp2build -> soong workflows correctly regenerates the
build-globs.ninja file.
Test: soong integration tests for null soong->soong, bp2build->bp2build and bp2build->soong builds.
