testing/protocmp: make Message implement proto.Message

By having the Message type implement proto.Message, it can be passed
to other general-purpose protobuf functions such as proto.Merge.
This provides a convenient way to convert the Message back into a
concrete form that may be easier to work with.

A minor consequence of this change is that invalid messages are
converted to an invalid Message that preserves type information.
Previously, they were simply transformed to a nil Message.
