Add the necessary verifier plumbing for the new file-backed dynptr type. Introduce two kfuncs for its lifecycle management: * bpf_dynptr_from_file() for initialization * bpf_dynptr_file_discard() for destruction Currently there is no mechanism for kfunc to release dynptr, this patch add one: * Dynptr release function sets meta->release_regno * Call unmark_stack_slots_dynptr() if meta->release_regno is set and dynptr ref_obj_id is set as well.
