Add CreateHRGNFromSkRegion and update DesktopRootWindowHostWin to use it.
SkRegion can now be converted directly to HRGN, rather than via SkPath, thereby avoiding the lack of support for non-contiguous regions in the SkPath to HRGN conversion step.
This CL is deliberately a minimal fix, suitable for merging.
