Mrozek, Michal 4cb86b4045 Add debug flag that controls zero copy for CL_MEM_USE_HOST_PTR buffers. 
- when flag is enabled driver will not go with zero copy path for
CL_MEM_USE_HOST_PTR flag

- flag doesn't work in shared context where we must accept zero copy
storage.

Hoppe, Mateusz 76dd4ac1f3 service read_only memory passed to CreateBuffer 
- only when cl_mem_flags allows for read only memory
and USE_HOST_PTR is used

Dunajski, Bartosz 4f2a05ac88 Map/unmap enqueue fixes [2/n]: CPU operations on limited range 
- Curently each non-zerocopy CPU operation on map/unmap make a full copy
  using hostPtr
- This commit adds functionality to select specific range of copy
- Multiple mapping with different size is not supported yet,
  so copy will be made on full range for now. This is for future usage.

Dunajski, Bartosz 844f956244 Remove redundant/recursive checks in unmap operations 
- Some of the paths were made only for ULTs
- Params like mappedPtr were ignored
- Improve confusing method names
- Fix for memory leak in map shared buffer path (not tested code)
