Implement feature inheritance and legacy editions for upb.
This switches upb to using legacy editions for all proto2/proto3 logic. This does not yet enable code generation for editions protos (ie. we do not yet turn on `FEATURE_SUPPORTS_EDITIONS`), but with feature inheritance in place, this will be a much smaller follow-on change.
There is a ~10% increase in allocations, but only a ~1% increase in peak memory. There are some <5% increases in instructions and cycles, but apparently no increase in time:

```
This adds about 5Ki of code size. Some of this likely comes from the fact that we now link in `message/copy.c` to perform a deep copy of a FeatureSet proto.

Implement feature inheritance and legacy editions for upb.
This switches upb to using legacy editions for all proto2/proto3 logic. This does not yet enable code generation for editions protos (ie. we do not yet turn on `FEATURE_SUPPORTS_EDITIONS`), but with feature inheritance in place, this will be a much smaller follow-on change.
There is a ~10% increase in allocations, but only a ~1% increase in peak memory. There are some <5% increases in instructions and cycles, but apparently no increase in time:

This adds about 5Ki of code size. Some of this likely comes from the fact that we now link in `message/copy.c` to perform a deep copy of a FeatureSet proto.

Implement feature inheritance and legacy editions for upb.
This switches upb to using legacy editions for all proto2/proto3 logic. This does not yet enable code generation for editions protos (ie. we do not yet turn on `FEATURE_SUPPORTS_EDITIONS`), but with feature inheritance in place, this will be a much smaller follow-on change.
There is a ~10% increase in allocations, but only a ~1% increase in peak memory. There are some <5% increases in instructions and cycles, but apparently no increase in time:

```
This adds about 5Ki of code size. Some of this likely comes from the fact that we now link in `message/copy.c` to perform a deep copy of a FeatureSet proto.

Implement feature inheritance and legacy editions for upb.
This switches upb to using legacy editions for all proto2/proto3 logic. This does not yet enable code generation for editions protos (ie. we do not yet turn on `FEATURE_SUPPORTS_EDITIONS`), but with feature inheritance in place, this will be a much smaller follow-on change.
There is a ~10% increase in allocations, but only a ~1% increase in peak memory. There are some <5% increases in instructions and cycles, but apparently no increase in time:
