Bp2Build common properties auto-handling

Introduce `commonAttributes` & `fillCommonBp2BuildModuleAttrs used in
CreateBazelTargetModule

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

As initial user, the Soong `required` property will be
translated to Bazel's `data`.
