out/soong/prebuilt_info.json will contain information about whether
source or prebuilt of an apex was used. If prebuilt is used, it will
print the path to its prebuilt_info file. This file will be
used to pick a matching set of MTS test prebuilts.
Each apex will have an entry in this file with the following properties
- Name, mandatory
- Is_prebuilt, mandatory
- Prebuilt_info_file_path, optional
Implementation details
- Introduce a new `prebuilt_info` prop to `apex_set` and `prebuilt_apex`
- All apex module types will set a prebuiltInfoProvider in
GenerateAndroidBuildActions, including the source apex module types
- Create a `apex_prebuiltinfo_singleton` that visits all apex modules.
It uses `IsHideFromMake` to filter out the unselected variants of a
specific apex. This new singleton will create prebuilt_info.json
- Dist prebuilt_info.json for droidcore

Test: #modified trunk_staging.locally to select prebuilts of some
mainline modules. Spot-checked that `is_prebuilt` and
`prebuilt_info_file_path` get populated appropriately
