automate protoc-gen target, make it part of build target

[guowenjian90]

there are two issues stopping automate protobuf generate in build.

1/ generating go types and grpc stub requires protoc and these two go protoc plugins.
protoc has to be installed separately using ' apt install protobuf-compiler' which I have not automate it in Makefile.

2/ there is a another argoproj/argo-rollouts#1091 (comment), actually need to modify a few k8s files code to set full package name to work around it.

tried to use 'M' go_opt when execute protoc, but not working, has to manually modify a few generated a few k8s protobuf files
to use full package name, files are listed in Makefile.
