- Re-vendored protobuf at v36.0 and regenerated all in-tree gencode.
- Excluded the cpp_file_options and json_enumvalue_options gencode that upstream
started shipping in the release artifacts; the .proto sources they derive from
were already excluded.
- Added the two lite-runtime sources our gencode actually reaches, type_id.cc and
unknown_field_set_lite.cc, and exported the four headers the built lite sources
newly reach. arena_allocation_policy.cc is also new to libprotobuf_lite_srcs but
defines nothing, so it stays out.
- Bumped the Java/Maven protobuf version to match.
