This is to simplify the process of resolving label + exclude labels
across the various configuration axes we have and across the various
properties/modules that use this behavior.

This CL adds support for cc_library to correctly split c, as and cpp
srcs in shared/static nested props, as well as splitting
the *filegroup* deps in those props, where each filegroup is expanded
into its own c, cpp and as srcs filegroups. This ensures that the
correct sources go into cc_library_static's underlying cc_libraries for
c, cpp and as sources respectively.
See the bp2build conversion test for a better visualization.

LabelListAttribute support was already added, but LabelAttribute support is needed for cc_import rules.
Test: Added unit test for version_script, which is the only supported LabelAttribute so far.

This change enables checked-in BUILD files like
prebuilts/clang/host/linux-x86/BUILD.bazel to be merged cleanly with the
bp2build generated one into the synthetic workspace.
The checked-in BUILD file contains a package() declaration that bp2build
also generates. To avoid double declaration, the BUILD file writer now
checks if the BazelTargets contain handcrafted targets. If so, it
delegates the package declaration to the handcrafted BUILD file instead.
This change also sorts the bp2build targets before the handcrafted ones,
and adds a section header to demarcate the two sets of targets.

This allows removal of almost all current items from the mixed build
denylist, which were previously broken due to being unable to separately
control flags for compilations of different languages within the same
target.
Note that this does not appropriately implement asm/c srcs and flags for
either the shared variant or the static variant. This will require a
followup.

Change-Id: I79eb6e8ec1d415bd50d12105da4cf97101f95474
There are two pieces to make this work:
1. Local include paths must include $(BINDIR)-relative paths, to support
generated headers in those directories.
2. The srcs that bp2build outputs for BUILD targets must include labels
for targets given in generated_hdrs and generated_srcs.
Support for exported_generated_hdrs intentionally deferred.
This allows us to remove several targets from the bp2build denylist.
Some are moved to the mixed build denylist, because genreated headers are
still unsupported in mixed builds.

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).

This now works with --features no_copts_tokenization. With tokenization,
the escaped empty string '\"\"' became an actual empty string '' on the
command line, setting -DWILDABBR to the wrong value.
However, no_copts_tokenization unveiled other problems with Android.bp
flags, such as spaces in existing cflags like
https://cs.android.com/android/platform/superproject/+/master:bionic/libc/Android.bp;l=288;drc=a0a4a6c2967b5b3c02c951ea1145f32ed5564ab9
- this trips up Bazel's copts when generated literally, so the
fix (other than splitting on space and making Soong accept strings that
don't start with dashes as cflags) is to make bp2build split cflags on
spaces before generating them as copts.

Then plumb them to LabelAttribute.
This refactoring is required because the previous implementation did not
handle properties in shards other than the first one (e.g.
version_script) well. In addition, it also makes the code paths between
bp2build and analysis more similar.

This combines properties among "multilib" and "arch" stanzas in selects
generated by bp2build.
With this fix, libc_gdtoa may be removed from the denylist.
This change also refactors a portion of arch.go, specifically bp2build's
arch mutator, adding a number of comments along the way, to hopefully
make this code clearer for future readers.

The comment on the interface of GetDirectDep states if there are
multiple deps with different tags, the first will be returned; however,
the current behavior is to panic if there are multiple deps. The
behavior now:
* a single dep, return the module and tag
* a single module with different tags: return module with first tag
* multiple modules: panic
* no module: return nil, nil

In a non-top level Android.bp file, exclude_srcs was not working at all
due to a bug in expandSrcsForBazel. GlobFiles was expanding a glob
relative to root, but the expandedExcludes list was relative to the
module dir, causing the glob function to not consider the
expandedExcludes list at all.
Add tests to demonstrate that this is working now.
