It now handles adding .bp files and changing globs.
In order to do this, depfiles are now written separately from RunBlueprint.
This is necessary due to the confluence of a number of seemingly
unrelated factors:
1. The glob filelist dependencies are discovered in globSingleton
2. Singletons need to be registered because otherwise singleton module
types panic
3. Singletons don't work because they require mutators bp2build does not
run
Due to (1), we would need to run the glob singleton. However, due to (2)
and (3), we can't run singletons and have to run Blueprint with
StopBeforeGeneratingBuildActions, which is when the build actions
writing glob files would be generated. So what happens is:
1. When bp2build is run, the glob singleton is disabled
2. At the end of bp2build, the list of glob files is artifically added
to the depfile of the workspace marker file
3. When build.ninja is generated, the Ninja file containing the glob
list file is written by the now-active glob singleton

This is done by setting the INTEGRATED_BP2BUILD environment variable
when invoking the build.
Even though the name of the marker file insinuates that a Bazel
workspace is already created, this is not the case yet.
An issue that remains is that a .d file is not written for the marker
file so it won't be rebuilt if a .bp file changes. Fixing this requires
delicate surgery because writing the .d file is the result of delicate
interplay between Soong and Blueprint.
There are also a number of semi-related fixes:
- The name of soong.environment.{used,available} is now on the command
line of soong_build (soong_docs is still special cased because its
command line in the Ninja file is taken from the os.Args of
soong_build so it's not trivial to remove the --{available,used}_env
from it
- bp2build writes a separate soong.environment.used file
- I had to call SetAllowMissingDependencies() separately when creating
the android.Context for bp2build so that bp2build runs in the
integration tests (it was not obvious how not to do this)
- Fixed a number of integration tests where a command with an expected
exit code of 1 was used as the last one in a test case, thereby
breaking the test suite

Sbox preserves the permissions of input files when copying them into the
sandbox. A read-only file copied into the sandbox multiple times causes
a permission denied error on the second write. Building in Bazel results
in more read-only files, which triggers the issue on existing sbox rules
with duplicate input files. Remove the destination file when copying if
it exists.

The current implementation causes inputs listed in an rsp file used with
sbox to be duplicated 3 times in the build.ninja file; once as a
dependency of the rule, once in the rspfile_content field of the rule
with the paths rewritten to be relative to the sandbox, and once in the
rule to write the sbox manifest. When RBE is enabled it also gets a
fourth copy in the list of files to be treated as inputs by rewrapper.
Reduce this to a single copy by using "$in" for the rspfile_content so
that the files only have to be listed in the input dependencies of the
rule, and then add support to sbox to rewrite the rsp file while copying
it into the sandbox, and pass it to rewrapper as well.

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.

This is achieved by writing soong.environment.used in Main() instead of
as a side effect of a singleton. This makes a difference because build
actions are not generated when GENERATE_BAZEL_FILES=true is set,
therefore the side effect did not happen.
Arguably, Main() is made worse by this change, but I don't want to
tackle the problem of readably determining which mode soong_build is
running in in this change.

This requires linking Blueprint into soong_ui. It lets us avoid the
complicated dance of Ninja files and shell scripts: now the information
as to how soong_build is built is passed directly to Blueprint using a
struct that contains all the information the command line arguments used
to contain.
The ability to run Blueprint from the command line is kept (for now).
Some variables in bootstrap/command.go needed public accessor functions
because soong_build reads them. This will be disentangled by moving the
flag parsing to soong_build.
The presence of the flag definitions in Blueprint means that soong_ui
now also accepts them. This is not a problem in practice because they
are ignored and because soong_ui itself is hidden behind a few layers of
shell scripts.
Test: Presubmits + the new bootstrap_test.sh .

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.

Implement bp2build codegen as a discrete step that runs after an
alternatively registered pipeline of mutators, instead of a

bp2build codegen requires a Context that supports VisitAllModules and

conforms to PathContext by adding two method implementations.

A SingletonModule is halfway between a Singleton and a Module. It has

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.
