Each conversion required defining a separate mutator, which will each
operate on _all_ modules and requires each to repeat checks whether the
mutator should operator. Instead, we introduce a single mutator and
modules can define a ConvertWithBp2build to implement bp2build
conversion for that module.

This also removes the special-case filegroup from mixed builds
buildroot; no special handling is required. Since we're currently
hardcoding linux_x86_64 as our host platform, it should be fine
to continue assumping that hardcoded host for now.

target.kind was a field that existed for only a few months, and have
been removed from Bazel. This is needed to update to a newer Bazel version.
Also, this reverts filegroups to be queried for a specific arch again,
but leaving file targets in the common arch (which is correct, anyway).

Adapt `bp2BuildInfo` to use `commonAttrs` instead of `Name`.
And thus also all downstream users of `CreateBazelTargetModule`.

This builds cap_names.list.h, which uses an eponymous filegroup
"generate_cap_names_list.awk" in Soong, but uses the file target
directly in Bazel.
This also improve filegroup support for mixed builds, by issuing a
cquery call _without_ arch. Filegroups in Soong don't have configurable
properties, so don't generate Bazel filegroups into buildroot's
config_nodes (which was x86_64 by default).
The mixed_build_root now looks like this:
```
config_node(...)
config_node(...)
config_node(...)
config_node(...)

with the same name.
Also add capability to test for errors raised in bp2build mutators /
contexts.
This CL does two things to filegroups:
1) If the filegroup has only 1 source file with the same name as itself,
don't generate a filegroup target. Instead, dependents will depend
directly on the Bazel file target instead.
2) If the filegroup has more than 1 source file and 1 of them has the
same name as itself, the bp2build mutator will error out. If bp2build
on CI passes, it means that the source tree / product we're testing
against does not have such a case (which seems to be true for most
source trees).
Either way, this will allow us to be unblocked for most of the errant
filegroups (case 1) in the tree.

A performance improvement for bp2build as Blueprint/Soong no longer have
the overhead of additional modules. The creation of these modules
results in:
* traversal of additional modules for each subsequent mutator
* synchronization over a go channel to collect newly created modules:
https://cs.android.com/android/platform/superproject/+/master:build/blueprint/context.go;l=2594,2600;drc=1602226f23181b8c3fbfcaf3358f0297e839d7d3
We avoid both of these by storing the information directly in the
underlying module.
Also as a fringe benefit, removes some necessary boilerplate for
conversion.
For benchmarks, reduces runtime ~1% for 1% converted, ~24% for 100%
converted. See more: go/benchmarks-for-https:-r.android.com-1792714

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.

This CL adds the support for specifying lists of directories in
build/soong/android/bazel.go, which are then written into
out/soong/bp2build/MANIFEST. Using this configuration,
modules/directories can either default to bp2build_available: true or
false, while still retaining the ability to opt-in or out at the module level.
It also ensures that ConvertWithBp2Build returns true iff the module
type has a registered bp2build converter.
