Fix QSpinBox clipping issue on Mac when frame=false

This was a regression from 5.0. Since we still require a minimum
height to be present in order for the spin buttons to draw correctly,
we require the same height from a spinbox without a frame as one
with a frame.

QNX: Add option to disable screen power save from an envvar

Qt itself has no API for disabling screen power save, although this
might make an interesting addition at some point.

Instead we make the QNX QPA plugin determine if power save should be
disabled from the QQNX_DISABLE_POWER_SAVE environment variable. This
would typically be set in the application's bar descriptor file.

QNX: Fix screen rotation

The behavior introduced by qtdeclarative's 475d1ed4f6a2 mandates that an
expose event follows a geometry change event. The fix for this uncovered a bug
on the raster backing store which caused the rotation to break on QtWidgets.
The problem was rooted on the assumption that the
QQnxRasterBackingStore::flush() method was only called after paints to the
backing store surface, which was discovered to be a false assumption. Flushing
the backing store can occur in other circunstances, which are out of scope on
the context of the QNX plugin.
