Originally, when the prebuilt_apex was first created, it selected the
source to use in its DepsMutator. It did that because that was a
convenient place for it to perform that work which had to be:
* After the arch mutator had run so MultiTargets() was available.
* Before the prebuilt_select mutator runs as that relied on the Source
property to have been set.
Change 064b70c9 then duplicated the call from the DepsMutator of the
deapexer module type that was added as part of the work to make dex
files available for hiddenapi processing.
Change 356f7d45 moved it out of the the DepsMutator methods into its
their own mutators, presumably because it interfered with the
Soong -> Bazel conversion work.
This change improves the existing PrebuiltSrcsSupplier mechanism to
support reporting errors so that the logic for selecting the source can
be done on demand rather than in separate mutators.
The main complication was that PrebuiltSrcsSupplier is called with a
BaseModuleContext for both source and prebuilt modules so it cannot use
any methods on it that are related to the current module. That
necessitated adding MultiTargets() to android.Module.

Previously when an APEX whose min_sdk_version is set is linked to an
external library providing multiple versions of stubs, the
maximum version that is less than or equal to the min_sdk_version was
chosen. For example, if the versions of a library stubs are 28, 29, 30,
and 31, then APEX with min_sdk_version: 29 linked to the version 29 of
the stub.
This was to ensure that the APEX doesn't use any new APIs whose
existence can't be guaranteed.
This however imposes a severe restriction that the APEX can never use
new APIs even when the APIs are actually available: i.e. when the
APEX is running on a newer platform.
With the recent work about unguarded availability, using the future APIs
became much safer. When you use an API that is newer than your
min_sdk_version, the API is automatically declared as a weak symbol
(thus no link error at runtime), while the call to API is guaranteed to
be guarded with the `__builtin_available(...)` macro.
So, there really is no reason to use the old version of the stub. We can
always use the latest version of stub safely.

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.

The 'vendor_snapshot' module is required to every cc_library to check
if the dependencies need to be rewritten to the snapshot modules or
not. However, as the 'vendor_snapshot' module has dependencies to the
snapshot modules, the dependency to the 'vendor_snapshot' module
creates circular dependencies.
The dependency from the 'vendor_snapshot' to the snapshot modules is
required only to read the module names of the snapshot modules. We
may remove the dependency by setting the name of the snapshot modules
directly.

Previously, it was assumed that generated headers must be arch specific
and so prevented the fields referencing the paths to those headers from
being automatically optimized by the sdk generation code. That is not
always the case, e.g. with headers generated from protos so this change
allows those fields to be optimized.

Previously, the snapshot handling code did not preserve the directory
structure of generated include directories and instead just copied the
headers into the same module specific directory and added that single
directory to the export_include_dirs (or similar) property.
That had a couple of issues:
* The include directory was repeated in the ..._include_dirs property.
* It did not work when the include directories overlapped.
In the latter case it had a couple of issues:
* Code which compiled fine against the source would not compile against
the prebuilt.
* Header files were duplicated in the output.
e.g. assume the following generated header file structure:
foo/
foo.h
bar/
bar.h
baz/
baz.h
When the sdk snapshot was passed include directories of "foo", "bar" and
headers of "foo/foo.h", "bar/bar.h", "bar/baz/baz.h" it would generate a
snapshot with the structure:
include_gen/
foo.h
bar.h
baz/
baz.h
And:
export_include_dirs: ["include_gen", "include_gen"]
However, when the include directories overlapped and include directories
of "foo", "bar" and "bar/baz" were passed in the directory structure
would be the same and the export_include_dirs would contain 3 usages of
"include_gen".
That meant that source code which used the following would build
against the source (because it would find "baz.h" in the "bar/baz"
include directory) but would fail when built against the prebuilts
because the "include_gen" directory did not contain "baz.h":
#include "baz.h"
This change preserves the input directory structure for generated files
in a similar way to how it does it for source files. So, the snapshot
structure looks something like this:
include_gen/
foo/
foo.h
bar/
bar.h
baz/
baz.h
And:
export_include_dirs: [
"include_gen/foo",
"include_gen/bar",
"include_gen/bar/baz",
],

Previously, a cc library that included .aidl, .proto and/or .sysprop
files and exported headers generated from at least one of those types
would actually export generated headers from all of them.
While headers generated from .sysprop files are always exported those
generated from .aidl or .proto should only be exported when explicitly
requested.
This change treats them separately as expected. It has the potential
to break the build as it could reduce the set of headers exported and
so a dependent module that needed those would break. The fix in that
case is to simply add one (or both) of the following to the module
that previously exported those headers:
aidl: {
export_aidl_headers: true,
}
proto: {
export_proto_headers: true,
}

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.
