f8231dd0ea Platform mapping-based product config
This allows us to set product variables as build settings instead
of loading them from a target's provider, which further allows us
to read product config variables in transitions.

c9508aac4c Load starlark files from soong
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.

520e88b740 Avoid deleting bp2build directory
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)

Test: New integration tests
Test: Manual benchmarking in conjunction with persistent bazel server

83e787e837 Add a new CreateSoongInjectionDirFiles function
- This is a wrapper function for all files in soong_injection directory.
This should prevent an error in the workspace generated for
api_bp2build.
- Rename the existing CreateSoongInjectionFiles fn and make it package
  private to prevent confusion

(The subsequent CL in this stack should contain a smoke test for
api_bp2build)

b85d1a15cc Bp2build support for multiple product configs
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.

6117450ead bp2build: add converted modules to codegen metrics, and remove the
compat layer.

The list of converted modules is used for tracking bp2build progress.

The module_name_to_label aliases weren't really adding much value to
mixed builds, so let's drop the feature for now and simplify the code.

bf61afb7f7 bp2build: export some cc toolchain flags into Starlark.
This CL exports common/global/device/host clang/ld/ldd flags
from their Ninja variable initialization locations in
cc/config/global.go and cc/config/clang.go to make Bazel's cc_toolchain
and Soong's cc actions more consistent with each other.

This does not handle env-dependent or arch-specific toolchain flags
yet (logic in compiler.go and linker.go).

12b4c2706d bp2build: add allowlist for package-level conversions.
This CL adds the support for specifying lists of directories in
build/soong/android/bazel.go, which are then written into
out/soong/bp2build/MANIFEST. Using this configuration,
modules/directories can either default to bp2build_available: true or
false, while still retaining the ability to opt-in or out at the module level.

It also ensures that ConvertWithBp2Build returns true iff the module
type has a registered bp2build converter.

164e0867fc bp2build: add a simple UI to report migration progress.
Sample output:

[bp2build] cc_library_headers: 5 targets
[bp2build] cc_object: 5 targets
[bp2build] filegroup: 4 targets
[bp2build] genrule: 4 targets
[bp2build] sh_binary: 1 targets
[bp2build] Generated 19 total BUILD targets from 39270 Android.bp modules.

This CL adds an additional CodegenMetrics return value to
GenerateBazelTargets calls, which are called from bp2build, queryview,
and their tests. For this UI, we only want to use it for bp2build, and
not queryview or tests, since it's not useful for the former, and can
pollute the CLI for the latter.

33832f96e0 bp2build: introduce CodegenMode.
The CodegenMode enum helps to differentiate between bp2build and queryview modes of generating BUILD files from the Soong module graph.

bp2build is used for generating BUILD files from an unconfigured Soong module graph for Soong->Bazel conversion, whereas QueryView is a front-end for querying the existing Soong configured module graph with Bazel query.

This CL creates the framework necessary for generating

BazelTargetModules are code-generated into Bazel targets in BUILD files.

See the follow-up CL for examples of creating filegroup/genrule
BazelTargetModules.

with no BUILD files, because there are no BazelTargetModules in the

daa54bcbba Implement code-generation step for bp2build.
Implement bp2build codegen as a discrete step that runs after an
alternatively registered pipeline of mutators, instead of a
presingleton.

bp2build codegen requires a Context that supports VisitAllModules and
PathContext, so this CL also makes a BpToBuildWrapperContext that
conforms to PathContext by adding two method implementations.

Test: GENERATE_BAZEL_FILES=true m nothing && bazel query //... --config=bp2build | wc -l # 31433
Test: m queryview && bazel query //... --config=queryview # 63638

2dd9ca422d Refactor queryview.
Splits queryview into queryview and bp2build. The latter runs as a
presingleton (could be converted to a singleton). This prevents needing
to run soong_ui a subsequent time to build the query. Queryview remains
as a separate step to prevent increasing runtime due to this generation
every time Soong runs.

Currently this is running as a presingleton as this gives a translation
of Android.bp files after only LoadHooks have run, no mutators.
