14a8bda31e bp2build: split as, c, and cpp srcs for cc_library
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.

af24cdd99f Split asm and c flags and srcs in bp2build output
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.

45dec1072b bp2build: avoid adding deps on system_shared_libs temporarily.
At least until libc and libm builds, which are the common values in
system_shared_libs. We don't have a way to break the cycle of:

libstdc++.so (system_shared_libs) -> libc.so -> ...(whole_static_libs) -> libstdc++.a (system_shared_libs) -> []

because bp2build just sees it as:

libstdc++ (system_shared_libs) -> libc -> (whole_static_libs) -> libstdc++ (system_shared_libs) -> libc -> ...

therefore creating a cycle.

This CL punts the problem for now by ignoring system_shared_libs in the cc deps mutator, with a TODO.

484e50aa7c bp2build: support generated sources and hdrs
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.

5f51839d0d Refactor GetTargetProperties().
This is so that its implementation is more amenable to implementing
`target: { android_arm: { ... } }` and the like.

In addition, add a Boolean return value to getChildPropertyStruct() and
use it at every call site so that we only merge property structs when it
makes sense.

3950cd6ed4 bp2build: remove libc_tzcode from denylist.
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.

598dd00236 Refactor how bp2build gets arch-specific props.
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.

ed9c17d033 bp2build: refactor/standardize cc_* bp2build converters
This CL refactors the cc* bp2build converters to use the common
attribute extractors in cc/bp2build.go.

This also adds include_build_directory to be handled by the compiler
attr extractor to generate recursive headers as inputs.

This also turns include_dirs and local_include_dirs into the
execroot-relative -I flags.

e.g. if a module in  bionic/libc has "private" in local_include_dirs,
the "-Ibionic/libc/private" copt is generated for it.

91220d7334 Add os/target configurable selects for label list attributes.
This CL is pretty large, so I recommend starting with reading the newly
added tests for the expected behavior.

This change works in conjunction with the linked CLs in the Gerrit topic.
Those CLs add support for new platform() definitions for OS targets
specified in Soong's arch.go, which are configurable through
Android.bp's `target {}` property. It works similary to previous CLs
adding support for the `arch {}` property.

These configurable props are keyed by the OS: android, linux_bionic,
windows, and so on. They map to `select` statements in label list
attributes, which this CL enables for cc_library_headers' header_libs
and export_header_lib_headers props.

This enables //bionic/libc:libc_headers to be generated correctly, from:

    cc_library_headers {
        name: "libc_headers",
        target: {
            android: {
                header_libs: ["libc_headers_arch"],
                export_header_lib_headers: ["libc_headers_arch"],
            },
            linux_bionic: {
                header_libs: ["libc_headers_arch"],
                export_header_lib_headers: ["libc_headers_arch"],
            },
        },
        // omitted props
    }

to:

    cc_library_headers(
        name = "libc_headers",
        deps = [] + select({
            "//build/bazel/platforms/os:android": [
                ":libc_headers_arch",
            ],
