proto, runtime/protoiface: add support for fast-path marshaling
Allow message implementations to provide optimized versions of standard
operations. Generated messages now include a ProtoReflectMethods method,
returning a protoiface.Methods struct containing pointers to assorted
optional functions.
The Methods struct also includes a Flags field indicating support for
optional features such as deterministic marshaling.
Implementation of the fast paths (and tests) will come in later CLs.
