77e8b7b6d2 bp2build: add bazel_module: { bp2build_available } prop.
This CL adds a per-target allowlist to instruct bp2build on which modules it should generate Bazel targets for.

40067de675 bp2build: support Starlark rules and load statements.
This CL adds support to bp2build for declaring the location of the
Starlark rule definition when creating BazelTargetModules. This is
needed for non-native rules that needs to be loaded from .bzl files
somewhere in the tree.

Since load statements are aggregated at the top of the BUILD file, away
from the targets that actually use them, this CL also introduces an
abstraction to group BazelTargets together and compute their load
statements and target string representations separately, allowing load
statements to be decoupled and written into a BUILD file before the
targets themselves.

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.

Test: go test

288e2babde queryview: prefix internal attribute names.
There's a module type in internal main that uses the module_deps
property, which clashes with QueryView's module_deps attribute. A fix is
to prefix the attribute as soong_module_deps to avoid the conflict.

While we're at this, rename the other internal attribute names to be
consistent as well.

Test: soong tests

Test: m queryview && bazel query //... --config=queryview

7385067640 bp2build: framework for generating BazelTargetModules.
This CL creates the framework necessary for generating
BazelTargetModules from regular Soong Android modules.
BazelTargetModules are code-generated into Bazel targets in BUILD files.

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

Test: GENERATE_BAZEL_FILES=true m nothing # creates out/soong/bp2build
with no BUILD files, because there are no BazelTargetModules in the
module graph.

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.

Test: go tests
Test: m queryview && bazel query --config=queryview //...
