The fixes are
- Dedupe the dir list. Since we partition the proto srcs per pacakge and
then iterate the map, a single include directory was being listed
multiple times
- Drop target_compatible_with from these proto_library targets. The
compatibility will be enforced at the top-level <lang>_proto_library.

This is a fix similar to aosp/2707793. This adds manual tags to the
top-level proto_library created in the root package, plus any
dynamically created proto_library targets for proto.include_dirs. These
proto_library targets might not specify their deps correctly and might
be unbuildable.
(We need to keep these targets because they provide a ProtoInfo for
cc/java/py source gen)
Test: go test ./bp2build

Soong's proto.include_dirs becomes the -I path for aprotoc cpp code
generation. This does not translate well to Bazel because it runs this
action in a sandbox. Even if we construct an -I path, the .proto files
will not be there. This CL attempts to handle this kind of dependency
automatically via bp2build.
For this hypothetical example
```
foo.proto # contains `import bar.proto"
Android.bp # cc_library {srcs:"foo.proto", p.include_dirs:["subdir"]},
subdir/bar.proto
```
Implementation details for CcProtoGen of foo
- Glob the labels of .proto files for each includeDir, and create a
proto_library that encapsulates them.
- Since Bazel poses a contraint that proto_library target needs to be
in the same pacakge as the .proto file, the proto_library might be created
in a subdirectory with an import_prefix
- Add bar's proto_library as transitive deps of foo's cc_proto_library.
This will be added to -I during aprotoc. We cannot add them to `deps`,
otherwise bar's symbols will be statically linked into foo's .a
file.
Implementation details for clang compile of foo
At the end of CcProtoGen, we have converted foo.proto
to .cpp/.h files. To compile them to .a files, we need the .h files
generated from bar.proto. Soong specifies this at the
top-level cc_library soong module, so add those deps as the
implementation deps for clang compile.
(Will add support for java in a follow-up CL)

This is a fix for aosp/2693190 that handled .proto files that end up in
different bazel packages. It did it by creating proto_library targets in
the correct bazel package.
Changing the granularity causes issues if the the new proto_library in
the subpackage imports a .proto file from a parent package or a
different package. e.g.
```
tmp
├── foo.proto
└── subdir/import_foo.proto # contains an `import "foo.proto"`
└── subdir/Android.bp # package boundary
├── Android.bp # contains a cc_library with foo.proto and
# subdir/import_foo.proto
```
At ToT, the ProtoInfo we provide to CcProtoGen is correct, but the
proto_library in subdir/BUILD will not compile because it does not have
a dep on the proto_library in ./BUILD
This CL creates a workaround by adding `manual` to the proto_library
targets. This CL is based on the assumption that the buildable unit in
bp2build is cc_library_*, and not proto_library necessarily (atleast
till we do a manual/automated cleanup)

Bazel poses a strict requirement that .proto files and proto_library
must be in the same package. This CL handles this automatically by
creating the proto_library in a separate dir/package if necessary
Implementation details
- Partition the `srcs` by package. `srcs` has been computed using
`transformSubpackagePath`, so the information about packages is
available at this point
- Create a proto_library in each package by using
`CommonAttributes.Dir`. Collect all these additional libraries
and put them in `info.Proto_libraries` so that they get added as deps
of (cc|python|...)_proto_library
- Add an import_prefix to the proto_library in subpackages relative to
the current directory. This relies on the assumption that every src is
beneath the current directory (Soong will complain if a path in
Android.bp contains ../)
filegroup module type uses a separate code-path to create proto_library.
This will be handled in the next CL in stack.

By default, the artifacts generated by cc_binary and cc_library in Soong
track the module name. But Soong supports overidding this using the stem
property. e.g.
```
cc_library {

stem: "foo",
}
```
will generate foo.so

Note that this CL does not do the `CheckBadHostLdLibs` validation of
Soong. There are some different ways to do this, and these are being
discussed in b/216626461. It is likely that we will need to create a new
property `host_ldlibs` to do the validation. But for now, re-use

Create a select statement for every api_domain a library could be
included in. The stub/impl
selection heuristics per apex domain are
1. If dep has stubs and the api domain appears in dep's apex_available, use
impl
2. If dep has stubs and the api domain does not appear in dep's
apex_available, use stubs
(Category 3: If dep does not have stubs and the apex does not appear in
dep's apex_available, then a separate apex_available validation in Bazel
will emit an error).
Platform variants have been special-cased for now to use equality of
apex_available for stub/impl selection

The use case for this is for creating a select statement for stub/impl
selection. Since Bazel propagates apex_name from the top-level apex,
the source apex and test apex builds a specific library in two different
configurations. We need select statements for both these two
configurations, but this metadata might not always exist in Android.bp
since test apexes are not necessary to be listed in Android.bp files.
To overcome this, the select statements will be created per api domain
instead. This CL uses a naming convention to infer the api domain of
apexes.

These are created by bp2build in /build/bazel/rules/apex. Eventually
these config_settings should likely be colocated with the source apex
definition.
Another alternative was to make Bazel's apex a macro that generates a
config_setting. I did not pursue this further for now since it requires the
apex_available of every allowlisted cc_library to also be allowlisted.
This might not always be true (e.g. com.android.runtime)

in bp2build. The context here is that `-fvisibility=default` should
only be added for CFI if `-fvisibility=hidden` is not already
specified. This will be achieved using toolchain features. Note
that Soong itself never adds `-fvisibility=hidden`. This is only
ever added in the `cflags` property of a bp file.

Note this doesn't entirely match Soong's logic but is an improvement to
allow linking against implementation when two cc modules are
apex_available to the same module.
It is not possible to recreate the logic for "directly in" without
significant changes to bp2build as we do not add dependencies nor run
apex mutators. Rather than trying to replicate this, we would be better
off refactoring Soong to no longer support the "directly in apex" logic
and require users to correctly specify apex_available.

Since the source_library attribute of _cc_stub_library_shared was a
label attribute, the source library was added as a dependency of the
stub which doesn't always make sense. E.g. it caused validation actions
for the source library to run even when we weren't building the source
library.
This change converts the label attriubte to a string attribute so that
we don't add the dependency.
