Added methods:
Enum.Descriptor
Message.Descriptor
EnumType.Descriptor
MessageType.Descriptor
ExtensionType.Descriptor
Message.New
All functionality is switched over to use those methods instead of
implicitly relying on the fact that {Enum,Message}Type implicitly
implement the associated descriptor interface.
This CL does not yet remove {Enum,Message}.Type or prevent
{Enum,Message,Extension}Type from implementating a descriptor.
That is a subsequent CL.
The Message.New method is also added to replace functionality
that will be lost when the Type methods are removed.
