Optimize QBluetoothUuid ctors and make use of QUuid optimizations
Constexpr usage shifts the ctors to inline implementation. In addition,
the meta type registration has to be separated from the ctor
implementation. A global static variable takes care of this now.
This optimization speeds the ctor performance by factor 15.
