In C23, `false` is now of type `bool`, not `int`. This turned a couple places where `false` was returned instead of `NULL` into errors.
The workaround in upb for Windows's broken NAN macro causes an error in Clang under C23, `cannot compile this static initializer yet`, I believe because `0.0 / 0.0` is not valid in constant-evaluation. This seems like it's probably a legitimate result of C23 standardizing constexpr, although it _could_ be a clang bug. In any case, refine the workaround a bit, to avoid this problem.
I've also reverted the kUpb_FltInfinity/kUpb_Infinity back to their former definitions, as INFINITY wasn't broken by the windows header, only NAN.

Introduce a upb_MessageValue_Zero() function to use for the cases we do want a zero'd union (typically a zero MessageValue union is not needed)

This also increases compliance by adding `default_applicable_licenses` to several `BUILD` files that previously did not have it.

This CL is mostly a no-op, except that now google3-only code is actually stripped from OSS, instead of being preserved in `# begin:google_only` blocks.
This follows the conventions of the greater Copybara ecosystem.

This just behaves the same as the pre-existing upb_Message_SetMessage(), but with the intendended naming style (upb_Message_SetMessage should accept an arena and support extensions).

General test for it is done in Rust, and then extensions are tested in UPB as they're not currently supported in Rust-upb.

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.

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.
