feature: Add debug keys for chunking allocation and size

Related-to: NEO-7695

New debug keys added:

EnableBOChunking is now a mask
0 = no chunking (default).
1 = shared allocations only
2 = device allocations only
3 = shared and device allocations

MinimalAllocationSizeForChunking sets the minimum allocation
size to apply chunking. Default is 2MB.
