cmd/protoc-gen-go: treat extensions fields as proto2 in some places

The v1 generator doesn't include a "proto3" tag on extension fields,
even when the field is defined in a proto3 file. Match that behavior for
consistency. We can probably change this later if we want to; it's
unlikely anyone is depending on this behavior.

The v1 generator uses pointer types for extension fields, even when the
field is defined in a proto3 file. (e.g., *FooEnum instead of FooEnum.)
Match this behavior. We can't change this without breaking compatibility
in the generated code.
