Title: Add support for map rotation (hub #9330)

Includes widget to show and set map rotation.
Handle rotation in vector and raster renderers.
Ensure correct behavior of panning and zooming actions.

Drop compile-time defines for ARM and ANDROID, leaving only
the qreal based function to transform in place.

Update expected test results after eye comparison.
