The package module type was recently introduced, and its module name is
the full package path. queryview uses the module name as the eventual
target name in the generated BUILD files, so this causes a crash as seen
in b/179605762.
Workaround this by not generating package modules in the queryview
directory.

This is obviously not good build hygiene, but since Soong modules are in a global namespace, making BUILD files fully public will increase our velocity during the initial migration phases.
We'd want to lock visibility down to private by default as soon as possible, but for the purposes of migration, these will be public.

This CL brings the defaults mutators into bp2build, reusing the
implementation of flattening defaults from *_defaults module deps into
the modules themselves.
This is an approach to converge defaults semantics with Bazel, which
doesn't have existing equivalent abstractions, other than macros, which
require more infrastructure to be built.

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.

The previous implementation relied on the implicit registration of Bp2Build mutators, resulting in test non-hermeticity. Refactor bp2build tests to explicitly specify the bp2build mutators under test.

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.

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.

fully qualified label lookup mechanism, so while the BUILD targets are
queryable, they are not buildable (yet).

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.

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.

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.
