Previously, it stored an android.Context (no pointer) which while it
worked (because the current contents are themselves pointers) it is

Test: Prior to thi CL bp2build.symlink_forest event was missing in bp2build_metrics.pb after a clean mixed build
Change-Id: I53bfc4114a383c0d1f9c4c7945e7d4c69bc50b0c
This helps with incrementality a lot: the symlink forest must depend on
almost every directory in the source tree so that if a new file is added
or removed from *anywhere*, it is regenerated.
Previously, we couldn't do this without invoking bp2build, which is
quite wasteful because bp2build takes way more time than the symlink
forest creation, even though we do the latter in a very suboptimal way
at the moment.
This means that if a source file is added or removed (which does not
affect globs), we don't pay the cost of bp2build anymore.
Also refactored symlink_forest.go on the side. Too much state was being
passed around in arguments.
This change reimplements aosp/2263423 ; the semantics of not touching an
output file is the exact same as order-only inputs and the latter is a
bit fewer lines of code.
Test: Presubmits.

- the generating rule has `restat=true`, so its output need not have a newer timestamp to prevent it from rerunning on subsequent ninja invocations
- its dependents (so far only bootstrap.ninja's "build build.ninja") already have proper dependencies in the depfile, namely
1. Android.bp.list,
2. entries in Android.bp.list,
3. bazel.list and
4. entries in bazel.list
This change prevents symlink related changes from spuriously retriggering build.ninja

The generated Bazel workspace will only contain api specific targets.
This is feasible since these targets do not have any cross dependencies
with the targets in the bp2build workspace
The advantages of a new mode are
1. Does not pollute bp2build workspace with api targets
2. Does not block api targets with the current allowlist conversion
mechansims in bp2build
(In the future we might want to combine these two workspaces)
A Soong module type will generate a Bazel target if it implements
ApiProvider interface

This refactoring prepares for introduction of bazel prod mode, an

On the build servers, LOG_DIR is a subset of DIST_DIR, which encodes the
build number. This means that LOG_DIR is guaranteed to be different for
every build, and we'll never re-use previous soong runs on CI builds.
The current use case (writing out soong metrics) shouldn't care if the
value changes, so pipe the environment variable through, bypassing the
env dep checks. It's not clear if this is the only issue triggering
soong_build re-runs on the build servers, but it's a start.
Test: Change DIST_DIR, soong_build does not re-run.

This was accidentally removed in aosp/2094705. Among other possible
issues, this caused the "used environment variable" file to be omitted
from the depfile of soong_build during mixed builds, which would result
in soong_build not being subsequently retriggered during env var
changes.
Sendng this out as a quickfix, regression test to follow.

This large refactoring has both immense performance implications and
improves mixed builds complexity / usability. Summary:
1. Queueing calls to Bazel is done in a new mutator instead of a full
soong_build pass. Normal soong_build flow is interrupted (via a
functional hook in blueprint) to invoke bazel and parse its response.
2. Implementing mixed build support for additional modules is as simple
as implementing MixedBuildsBuildable. In this interface, define the
request that must be queued to Bazel, and then subsequently define
how to handle the returned bazel cquery metadata.
3. Mixed builds consists of only a single pass. This greatly
improves mixed build performance.
Result:
A 33% runtime improvement on soong analysis phase with mixed builds.
Caveats:
C++ BazelHandler handling still remains a bit of a mess; I did what
I could within this CL's scope, but this may require additional cleanup.
Test: Treehugger
Test: Verified that aosp_arm ninja file is bit-for-bit identical with or

This is necessary because GenerateAndroidBuildActions() is effectively a
mutator and therefore can change the data stored in each module.
Sometimes one wants to dump that data in the JSON module graph, and in
order to do so, actions need to be generated.
I briefly entertained removing StopBeforePrepareBuildActions(), but it
incurs a 10-second penalty on "m soong_docs" and "m bp2build" so I
decided to keep it.

Soong writes out text protos for the sbox manifests, and if those change
every time soong changes, we trigger rebuilds of significant portions of
the tree. This is very annoying when attempting to iterate on Soong, so
disable this functionality at the soong_build level.

They were a bit repetitive.

This makes soong_ui the only place where soong_build is invoked, thus
greatly simplifying the conceptual model of the build.
It comes with the slight limitation that now soong_docs (and queryview
and the JSON module graph) are not Make targets anymore, but I suppose
that's an acceptable loss.
The only place where someone depended on soong_docs from a Makefile is
removed in a separate change.

Before, we piggybacked on the implementation of regular soong_build and
wrote a fake build.ninja file to satisfy Ninja.
Now, instead, the JSON module graph is a a separate action in the Ninja
output file. This has the pleasant side effect that one can flip back
and forth between generating the JSON file and regular Soong without
loss of incrementality.
Side cleanup: write .d files in a slightly cleaner way.

In particular, the writing of build-globs.ninja and the collection of
glob list files for build.ninja.d is now done outside of the Blueprint
invocation.
This is useful because RunBlueprint() is sometimes called multiple times
in a single soong_build invocation and because now glob processing is
not hidden by the machinery of Blueprint.

They used to be defined in Blueprint but since it doesn't have a
separate existence anymore, we can consolidate all command line
arguments here.

by a simple Go function call and not by invoking a separate binary, so
command line arguments are not needed there.

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)

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.
