Auto generate recovery build.prop module

Implementation details:
- Introduce recovery_build_prop module type given that the build rule of
  the recovery partition's build.prop file is quite different from that
  of the other partitions' build.prop files.
- Modify the visibility of the Soong-defined build_prop modules to allow
  the recovery_build_prop module to depend on them.
- Auto generate the recovery_build_prop module and add it to deps in
  FsGenState.

Test: build soong generated recovery partition and inspect the content of the generated prop.default file
