upb users currently need to manually fetch a oneof field in order to clear it.
In this CL, we add a convenience method to do that in one fell swoop.

All of this information is still available by merging fixed_features and overridable_features. This new split will make validation easier for runtimes that need to do dynamic builds.
PiperOrigin-RevId: 625815212
The new fields fixed_features and overridable_features can be simply merged to recover the old aggregate defaults. By splitting them though, plugins and runtimes get some extra information about lifetimes for enforcement.

The only public target here is the edition defaults helper macro, which can be used by external runtimes and plugins. None of this code is C++-specific though, and should be organized higher up. Appropriate aliases are also placed at the top level for public targets

This updates all our text parsers and serializers to better handle tag-delimited fields under editions. Under proto2, groups were the only tag-delimited fields possible, and the group name (i.e. the message type) was guaranteed to be unique. Text-format and various generators used this instead of the synthetic field name (lower-cased group name) to represent these fields.
Under editions, we've removed group syntax and allowed any message field to be tag-delimited. This breaks those cases when adding new tag-delimited fields where the message type might not be unique or correspond to the field name. Code generators have already been fixed to treat "group-like" fields using the old behavior, and treat new fields like any other sub-message.
This change addresses the text-format issue. Text parsers will accept *either* the type or field name for "group-like" fields, and only the field name for every other message field. Text serializers will continue to emit the message name for "group-like" fields, but also use the field name for everything else.
This creates some awkward capitalization behavior for fields that happen to *look* like proto2 groups, but it won't lead to any conflicts or invalid encodings. A feature will likely be added to edition 2024 to allow for migration off this legacy behavior.

This is needed to make protobuf/bazel package minimal for other proto rules.
Keep 4 public bzl files in upb/bazel. They end up under protobuf/bazel, and they are legitimately used by other repositories.
Move upb_proto_library_internal/* under bazel/private. Those are utilities used in the rules. Moving them one level deeper makes protobuf/bazel package clean for other rules.
Move build_defs.bzl and amalgamation under /upb/bazel. Those are utilities used in the build.
Move lua.BUILD and python* uner /python/dist. Those are used in the WORKSPACE dependency setup.
