Mixed builds support for prebuilt_* targets

These targets do not have any build actions per se, but return a
PrebuiltFileInfo provider. Parse this info from cquery and generate the
appropriate installation rules and androidmk entries

Details
- Support the bp2build available properties. Not all properties have
  been converted by bp2build yet, and those are being tracked in b/207489266
- Create a addInstallRules helper function to reduce duplication between
  GenerateAndroidBuildActions and ProcessBazelQueryResponse

Test: unit test
