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.

c424b76f76 Support multilib properties in bp2build
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.

2b50ce669c Make GetDirectDep implementation match comment
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

4ecc67d3c5 bp2build: fix exclude_srcs in subpackages.
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.

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",
            ],
            "//build/bazel/platforms/os:linux_bionic": [
                ":libc_headers_arch",
            ],

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.
