Since statically tree shaken messages can never later become linked, we should not need to use any of the special code in the decoder. By using a distinct "empty" message type, we avoid triggering any of this special behavior. This avoids bugs around hazzers and other presence checks.
Also fixed a bug in the cmake staleness test that was causing test failures.

This was previously fixed in C++ (https://github.com/protocolbuffers/protobuf/issues/16549), but not ported to other languages. Delimited field encoding can be inherited by fields where it's invalid, such as non-messages and maps. In these cases, the encoding should be ignored and length-prefixed should be used.

The functionality is enabled when the proto_one_output_per_message option used by C++ Lite is enabled.
This mirrors the behavior of C++ lite protos.

The second assert in _upb_EncodeRoundTripFloat is raised if val is a nan. This fix just returns the output of first spnprintf.
I am not sure how changes to this repo are made so feel free to ignore this CL.
To test this, you could
1. Define a proto with a float field
message Test {
float val = 1;
}
2. In a python script, import the library and then set the val to nan and try to print it.
proto = Test(val=float('nan'))
print(proto)
This will cause a coredump due to assertion error:
assert.h assertion failed at third_party/upb/upb/lex/round_trip.c:46 in void _upb_EncodeRoundTripFloat(float, char *, size_t): strtof(buf, NULL) == val
Added the corresponding change to double too

This "feature" hasn't been implemented yet, but this puts a placeholder down to prevent compatibility issues in future editions. Once we provide versioning support on individual feature values, we don't want them becoming usable from edition 2023 protos

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.
