QFutureInterface: clean up mutex() method for Qt 6

Browse Source 
Ditch the QMutex *mutex() method that we had to keep around for binary
compatibility and drop the disambiguation argument of QMutex
&mutex(int) now that we don't need it anymore.

The lock_guard lines now look dangerously close to C++'s Most Vexing
Parse, so use braced initialization to make sure it's parsed as a
definition, not a declaration.
