Temporarily reverting back to previously reported value to avoid corner-case
regression. Intent is reintroduce as soon as regressions are rootcaused.

The previous name "pageSize2Mb" defined in
shared/source/helpers/constant.h is inconsistent to other variable,
i.e. pageSize64k.
Furthermore, it's a bit misleading because the page size is defined in
Megabytes (MB), not in Megabits (Mb).

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.

When upstream ioctl helper is created it will try to create small
allocation, adding I915_GEM_CREATE_EXT_SET_PAT extension. If it
succeeds, for all resources with valid pat index value it will then
explicitly program pat index value with gem create ext call.
PrintBOCreateDestroyResult value can be used to:
- print whether the set pat extension is supported by the kernel, when
ioctl helper is created
- print whether set pat extension was added for a given gem create ext
call and what pat index value was programmed

- Given a Base Pointer passed into Get Peer Allocation, then the base
pointer is used in the map of the new allocation to the virtual memory.
- Enables users to use the same pointer for all devices in Peer To Peer.
- Currently unsupported on reserved memory due to mapped and exec
resiedency of Virtual addresses.

It is possible that a module has so many kernels that the 4GB limit of
GPU VA is depleted when each kernel allocates a 64 KB page for its own
ISA. In such case, propagate the ZE_RESULT_ERROR_OUT_OF_DEVICE_MEMORY to
the API caller to indicate the actual problem.
Currently such scenario is not detected, the execution advances a bit
further and the following crashes do not let the user to easily
understand what happened.

When one process had exported and then opened IPC handle
of memory, then close function was called twice for the
same BO handle. It caused debugBreak() and aborted
an application.
This change allows multiple separate BOs to share one
handle. The last shared handle owner calls close() function.
