Commit 035ad74fdd introduced Py_gpiod_GetModuleAttrString() as a way to
get a module's attribute and was inspired by CPython's internal function
_PyImport_GetModuleAttrString().
CPython 3.14 added PyImport_ImportModuleAttrString() to the public
API [0] which allows us to use the standard function when available.
