Make use of write enable flag for mem bo map

Use drm/intel optimization for mem bo mapping in case of read or write.
So we could be possibly waiting less.

This also adds 'map_flags' check in clEnqueueMapBuffer/clEnqueueMapImage
for actual read or write mapping.

But currently leave clMapBufferIntel untouched which might break ABI/API.

v2: Fix write_map flag in clEnqueueMapBuffer/clEnqueueMapImage.
