Add new implementation of QSound class

Added a re-implementation of QSound, using functionality derived from
QSoundEffect. QSound API remains the same as the original 4.x version.

It offers both a static interface (with auto resource cleanup on sound
completion), as well as an object instance interface for more detailed
control.
