Jingwen Chen 5d8644990b bp2build: add configurable attribute (select) support.
This CL adds a basic framework to support configurable string_list
attributes, selecting on the Arch variant (x86, x86_64, arm, arm64).

It offers fine-grained controls to map individual configurable
properties (arch_variant) to configurable Bazel attributes, starting
with the string_list type for the copts property for cc_object.

This design is primarily motivated to have minimal boilerplate in
bp2build mutators, allowing anyone to opt-in configurable attributes,
and modify intermediate states before passing them on into the
CreateBazelTargetModule instantiator.

Jingwen Chen db12024524 bp2build: add support for cc_object's objs and exclude_srcs properties.
objs contains module references to other cc_objects that will be used
for linking later. This maps to cc_library deps.

Also support exclude_srcs, and added tests.

Test: bp2build generate, sync, bazel build //bionic/...

Jingwen Chen 164e0867fc bp2build: add a simple UI to report migration progress.
Sample output:

[bp2build] cc_library_headers: 5 targets
[bp2build] cc_object: 5 targets
[bp2build] filegroup: 4 targets
[bp2build] genrule: 4 targets
[bp2build] sh_binary: 1 targets
[bp2build] Generated 19 total BUILD targets from 39270 Android.bp modules.

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.

Jingwen Chen 8c1b97e01b bp2build: cc_object converter.
This CL introduces a basic bp2build converter for cc_object modules.
cc_objects maps cleanly to cc_library targets, but with -fnoaddrsig.

This CL also demonstrates generating include deps within a macro to
allow the cc_object compilation to depend on a relative-include header
within an include dir.

e.g. if "foo.cc" includes "android/log.h" and the latter is located at
"include/android/log.h", the autogenerated header deps would export
"android/log.h" correctly to the foo.cc upstream target.

Test: GENERATE_BAZEL_FILES=true m nothing && bp2build-sync write && bazel build //bionic/libc:crtbegin_so1
