Most plugins need to copy comments from .proto source files into the
generated code. Move this functionality into protogen to avoid
duplicating it everywhere.

When the generator parameter 'annotate_code' is provided, generate a .meta
file containing a GeneratedCodeInfo message describing the generated code's
relation to the source .proto file.
Annotations are added with (*protogen.GeneratedFile).Annotate, which takes the
name of a Go identifier (e.g., "SomeMessage" or "SomeMessage.GetField") and an
associated source location. The generator examines the generated AST to
determine source offsets for the symbols.
Change the []int32 "Path" in protogen types to a "Location", which also captures
the source file name.

This is a straight translation of the v1 API gRPC "plugin" to protogen.
Add a protoc-gen-go-grpc command. The preferred way to generate gRPC
services is to invoke both plugins separately:
protoc --go_out=. --go-grpc_out=. foo.proto
When invoked in this fashion, the generators will produce separate
foo.pb.go and foo_grpc.pb.go files.
