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.

Before this change, changes to any Android.bp file would not trigger a re-run of bp2build/Soong, since the depfile for Soong's main output, the build.ninja file, didn't contain the list of Android.bp files. bp2build only reran when Soong itself changed, which happens regularly while developing bp2build, but not at all while modifying Android.bp files.
This change correctly dumps the list of all Android.bp files in the tree to the depfile for out/soong/build.ninja, therefore correctly triggering a re-run of bp2build when any Android.bp file changes.
Test: GENERATE_BAZEL_FILES=true m nothing; edit an Android.bp file; GENERATE_BAZEL_FILES=true m nothing -> successfully re-runs and regenerates out/soong/bp2build.

bp2build is a Soong mode that returns as soon as the BUILD files are generated. This causes it not generate the build.ninja file, which the Ninja process executing soong_build itself expects to produce as an output. If there isn't an existing build.ninja file generated from a previous build, GENERATE_BAZEL_FILES=true m nothing will fail.
This CL generates the expected files as a workaround, and also makes GENERATE_BAZEL_FILES=true skip the Kati/Ninja steps in soong_ui since they aren't needed.

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 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.

A SingletonModule is halfway between a Singleton and a Module. It has
access to visiting other modules via its GenerateSingletonBuildActions
method, but must be defined in an Android.bp file and can also be
depended on like a module.

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.

Code refactoring has been done for logs directory logic code since
the bazel metrics directory depends on the log directory. For builds
that did not specify a dist directory, the log directory is under
out directory. With dist, the logs directory is under <dist dir>/logs.
This matters for Android CI builds where the metrics files are
placed under logs directory. With this change, the bazel metrics
directory and corresponding files will be under <dist dir>/logs
directory for Android CI builds.

This CL adds a new CONVERT_TO_BAZEL env var, and a bp2build goal. It
reuses the queryview architecture, but registers no mutators before
converting to BUILD files. This gives us a blank slate of the module
graph to work with, and create a shadow/alternate pipeline of mutators
to converge the Bazel BUILD graph to be semantically equivalent with the
Android.bp graph (after apply its current set of mutators).
The command to do so is:
$ CONVERT_TO_BAZEL=true m bp2build
To not clobber with queryview, the generated files are in
out/soong/bp2build.
Test: CONVERT_TO_BAZEL=true m bp2build && bazel query --config=bp2build //...

Previously in order to make use of dist entries with tag properties it
was necessary for each module type to be modified to store the results
of GenerateTaggedDistFiles(module) in the AndroidMkEntry.DistFiles
property. This change generalizes that mechanism to work across all
module types.
This change does improve the behavior of a couple of tests where
previously a dist with tag property was ignored because tagged dist
files were not available now it is used correctly.
Some module types do not implement OutputFileProducer interface and so
they cannot handle dist with tag properties. This change makes it an
error to attempt to do that. That necessitated adding OutputFiles(tag)
method to customModule in queryview_test.go as some of the tests in
that file used dist entries with tag properties.
Follow up changes will remove the code that was made redundant by this.
Test: m nothing
m dist sdk - before and after this change, compare result to
make sure that there are no significant differences.

The sbox tool is used to wrap genrule actions, and run them in a
temporary directory. Afterwards, the outputs are moved into their
proper location in the output tree. However, some tools embed the file
name of the output file (as passed to the tool) into the output file.
For example, the perfetto code generator script uses the output file
name to generate a C header guard when it generates
perfetto_src_base_version_gen_h/gen/perfetto_version.gen.h.
When using remote execution / remote caching, these genrule actions are
run locally whenever the output file doesn't exist, effectively making
them unique (across time and between users).
They then cause cache misses on all actions depending on these output
files as well as on transitive actions. In the above example, this
causes libperfetto.so to differ, which then causes all actions
depending on libperfetto.so to be rerun unnecessarily.
As a fix, this commit changes the sbox tool to use the sha1 hash of the
manifest path. The tool already seems to assume that there are no
concurrent runs of the same tool with the same manifest (otherwise
it would fail flakily depending on exact timing). It seems therefore
safe to use a temporary path deterministically derived from the
manifest path.
Test: ran multiple builds w/ remote execution; observe proper caching

The hardlink optimization attempts to save I/O by hardlinking input
files into the sandbox instead of copying them, but it never works on
a Linux build due to nsjail always making out and the source tree into
separate bind-mounted filesystems. If the optimization did work it
would actually cause build failures when it hardlinked the relative
bionic/libc/fs_config_generator.py symlink into the sandbox directory
without the target. Just remove the optimization for now since it
never works.
