Change protoV1.ExtensionDesc to directly implement ExtensionType
rather than delegating to one.
Unify the previous types protoiface.ExtensionDescV1 and
filetype.Extension in impl.ExtensionInfo. The protoV1.ExtensionDesc
type becomes an alias to ExtensionInfo.
This gives us:
- Just one implementation of ExtensionType.
- Generated foopb.E_Ext vars are canonical ExtensionTypes.
- Generated foopb.E_Ext vars are also v1.ExtensionDescs for backwards
compatibility.
- Conversion between legacy and modern representations happens
transparently when lazily initializing an ExtensionInfo.
Overall, a simplification for users of generated code, since they can
mostly ignore the ExtensionDesc/ExtentionType distinction and use the
same value in either the old or new API.
This is change 3/5 in a series of commits changing protoV1.ExtensionDesc
to directly implement protoreflect.ExtensionType.
1. [v2] Add protoimpl.ExtensionInfo as an alias for
protoiface.ExtensionDescV1.
2. [v1] Update references to protoimpl.ExtensionInfo to use
protoiface.ExtensionInfo.
3. [v2] Create protoimpl.ExtensionInfo (an alias to a new type in
the impl package) and remove protoiface.ExtensionDescV1.
4. [v1] Remove unneeded explicit conversions between ExtensionDesc and
ExtensionType (since the former now directly implements the latter).
5. [v2] Remove stub conversion functions.
