Add support for _q_platform_qnxWindowType QWindow property

Browse Source 
This dynamic property can be used to specify an explicit QNX window
type for a QNX platform window.  The _q_platform_ prefix makes it
possible to place the property on QWidget objects instead.  Existing
functionality ensures that any QWidget property whose name begins with
_q_platform_ is copied to the underlying QWindow object prior to
creation of the platform window.

Add _q_platform_ aliases for the dynamic qnxInitialWindowGroup and
qnxWindowId properties so that these properties can be also be
specified on QWidget objects.
