Add clEnqueueMapBuffer and clEnqueueMapImage non-blocking map support.
There is a unsync map function drm_intel_gem_bo_map_unsynchronized in drm, that can
be used to do non-blocking map. But this function only map gtt, so force to use map
gtt for all clEnqueueMapBuffer and clEnqueueMapImage.
V2: refined comment, and using map_gtt_unsync in clEnqueueMapBuffer/Image
instead of map_auto to avoid confuse.
