grpc_shutdownto execute shutdown immediately if it's called not from execution threads, which is free from the dead-lock case where original asyncgrpc_shutdowntried to address. This makes shutdown more deterministic so that unit tests can assume that all gRPC resources including threads are properly deallocated at the end of test. Note thatgrpc_shutdowncan still spawn a detached thread for actual shutdown when the finalgrpc_shutdownis called from the execution thread.Fixes: #23604
