- Updated `third_party/utf8_range` to 25.1 to be aligned with other protobuf (protobuf, upb, and utf8_range need to be updated at the same time as they're in the same github repo)
- Added a workaround to `extract_metadata_from_bazel_xml.py` to handle `utf8_range` migration. It used to be `@utf8_range//:utf8_range` and it will be `@com_google_protobuf//third_party/utf8_range:utf8_range` from the next Protobuf release. So the script needs this hack to support both.
Closes#35798
PiperOrigin-RevId: 603822623
This is a prerequisite for upgrading to protobuf 22.x
(upb and protobuf now depend on utf8_range)
Currently utf8_range isn't referenced by anything, but it's better to
bring the subtree in advance to make the protobuf upgrade PR smaller.
