Remote debugger should be checked only if interpreter paused on STW

[sergey-miryanov]

Feature or enhancement

Proposal:

Now it is checked every _Py_HandlePending call.

cpython/Python/ceval_gil.c

Lines 1361 to 1368 in 1dfe99a

	/* Stop-the-world */
	if ((breaker & _PY_EVAL_PLEASE_STOP_BIT) != 0) {
	_Py_unset_eval_breaker_bit(tstate, _PY_EVAL_PLEASE_STOP_BIT);
	_PyThreadState_Suspend(tstate);
	/* The attach blocks until the stop-the-world event is complete. */
	_PyThreadState_Attach(tstate);
	}

cpython/Python/ceval_gil.c

Lines 1431 to 1433 in 1dfe99a

	#if defined(Py_REMOTE_DEBUG) && defined(Py_SUPPORTS_REMOTE_DEBUG)
	_PyRunRemoteDebugger(tstate);
	#endif

Should we move this under if ((breaker & _PY_EVAL_PLEASE_STOP_BIT) != 0)? If yes, I have a PR ready.
