A performance improvement for bp2build as Blueprint/Soong no longer have
the overhead of additional modules. The creation of these modules
results in:
* traversal of additional modules for each subsequent mutator
* synchronization over a go channel to collect newly created modules:
https://cs.android.com/android/platform/superproject/+/master:build/blueprint/context.go;l=2594,2600;drc=1602226f23181b8c3fbfcaf3358f0297e839d7d3
We avoid both of these by storing the information directly in the
underlying module.
Also as a fringe benefit, removes some necessary boilerplate for
conversion.
For benchmarks, reduces runtime ~1% for 1% converted, ~24% for 100%
converted. See more: go/benchmarks-for-https:-r.android.com-1792714

- If no system_shared_libs is specified, bp2build writes no attribute
value. In this case, the bazel library macros determine the correct
default behavior.
- If any system_shared_libs is specified for any variant, then bp2build
writes the value verbatim. This includes if an empty list is specified,
as this should override defaulting behavior.
Note this defaulting behavior is incomplete and will be incorrect in
corner cases. For example, if, in an Android.bp, system_shared_libs is
specified for os.linux_bionic but not for os.android, then the bazel
default for os.android will be incorrect. However, there are no current
modules in AOSP which fit this case.
As a related fix, supports static struct for cc_library_static.
Also, removes some elements from the bp2build denylist.

system_shared_libs has been modified to have the same behavior as
the newly added default_shared_libs, remove default_shared_libs in
favor of system_shared_libs.
This reverts Ia2349d84c70e503916f90a5d2702e135248f73df and renames
the default_shared_libs property in cc_object (which never had
system_shared_libs) to system_shared_libs.

This fixes a bug which was a misunderstanding of soong properties:
Soong's cflags pertain only to C and C++ language, whereas bazel's copts
pertain to all three languages. This change ensures that asflags are
added as specifically asflags, and the 'copts' for the static library
macro pertains only to C and C++ languages.
This requires a somewhat hacky workaround for asflags, however: Since
assembly sources also need includepath-related flags, this duplicates
these flags between copts and asflags. To reduce verbosity of
bp2build-generated targets, this also ensures that asflags are omitted
in cases where there are no assembly sources.

Building against a locally-built libc besides bionic requires setting
system_shared_libs to avoid circular dependencies, but modules all
over the tree assume that system_shared_libs only affects modules
building against bionic. Add a new default_shared_libs property
that applies to all modules, which will generally be set in
arch-specific clauses to only affect the desired set of modules.

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.

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.
