The relative paths option for protoc generators doesn't work well when
it comes to dependencies. This simplifies the code generation to avoid
using `go generate` and to use one global command for protoc generation.
This is similar to https://github.com/docker/buildx/pull/2713 since the
same problems with code generation occur here too.

Remove gogoproto in favor of the standard protobuf compiler. This
removes any nonstandard extensions that were part of gogoproto such as
the custom types.
