makefile: rename codegen to protogen

Now that we have renamed the generate target to crds, it makes sense to also rename to codegen target to make it more clear that it specifically refers to protobuf codegen. Just as with make generate, we keep the old codegen target around to use as an alias for backward compatbility. We also remove the original protogen dockerfile as it is no longer needed. Instead, we can simply use the base cilium-builder image. Signed-off-by: William Findlay <[email protected]>
