pw_protobuf: Document the codegen-private namespace

Also, rename the private codegen namespace from pwpb_codegen_detail to
pwpb_codegen_private.

I recently got some CLs that actually were trying to use this private
namespace, which shows me that it's not sufficiently clear that users
are not meant to use them. I added some documentation, but for those who
don't read it, hopefully "private" is more recognizable than "detail".
