SWDEV-79445 - OCL generic changes and code clean-up
	- Add suballocations support for local(invisible) memory. It should significantly improve memory footprint and TLB usage with 2MB pages
	- Implementation uses BuddyAllocator provided in PAL
	- The chunk allocation size is 64MB, min allocation 4KB and max 4MB. GPU_MAX_SUBALLOC_SIZE controls the max size in KB
