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 allows us to, for certain modules, enable bp2build, but disable
mixed builds.
This facilitates easier iteration on these two features, as modules can
be incrementally "fixed" for bp2build, even if they are not ready for
mixed builds integration.

Previously, genrules which were used as generated_headers only
propagated the old Soong gen directory as an include path, even if the
genrule was managed by Bazel. With this chance, the gen directory of the
Baze output files are used in mixed-build mode.

Use an interface instead of a string to retrieve the value for
$(location) or $(locations) expansions in genrules to allow
delaying the evaluation until the RuleBuilderCommand is available.
This allows using helpers like RuleBuilderCommand.PathForInputs
to properly rewrite the values for sandboxing.
Also remove the standalone SboxPathFor* methods that don't operate
on a specific RuleBuilderCommand that are now unnecessary.

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.

If a genrule depends on a module that is disabled, in this case because
it is a device module in a host-only build, it can cause panics when
getPathsFromModuleDep retrieves a nil Path from the disabled module.

This effectively moves execution of Bazel actions outside of soong_build
