Calling `PyErr_NoMemory` without holding the GIL in `winconsoleio.c`

[aisk]

Bug description:

cpython/Modules/_io/winconsoleio.c

Lines 676 to 679 in 0ed497a

	Py_UNBLOCK_THREADS
	if (!newbuf) {
	sig = -1;
	PyErr_NoMemory();

PyErr_NoMemory will call _PyThreadState_GET, which will return NULL without holding the GIL and leading to crash.

A PR is on the way.
