QtWidgets: Use C string literals as keys

Addressing a comment from the review of QTBUG-98434. QSettings has been
already ported to use QAnyStringView keys so use C literals to call
beginGroup, setValue and value.

Since the constructor of QSettings does not have an overload for
latin1 strings, change the calls to use u""_s instead of _L1.
