Previous design allowed driver version to be no greater than 16-bit.
New design allows driver version to use (almost) whole 32-bit size limit.

There is a possibility that getGraphicsAllocation returns nullptr, so
accessing storageInfo would cause a Segmentation fault.
This change prevents that by simply nullptr checking.

When using ReturnSubDevicesAsApiDevices=1 to have
sub-devices-as-root-devices, then the driver should read the values
passed in the mask as those corresponding to the physical
sub-devices.
For instance, in a dual system with multi-tile device, we would have:
card 0, tile 0
card 0, tile 1
card 1, tile 0
card 1, tile 1
With:
ReturnSubDevicesAsApiDevices=0
ZE_AFFINITY_MASK=0,1
Then all tiles in card 0 and card 1 need to be exposed.
With:
ReturnSubDevicesAsApiDevices=1
ZE_AFFINITY_MASK=0,3
Then card 0 tile 0, and card 1 tile 1 need to be exposed.

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.

- Fixed IPC Event pools that are allocated for a single device such that
when opened thru IPC only that device handle can be used by the process
which opened the IPC event pool.
- IPC Event handle includes numDevices as a field to determine if the
root device index is the only index allowed for this event pool.

Sizing context (PVC):
When using LargeGRF (a.k.a GRF256) there are only 4 HW threads per EU
(instead of default 8). Together with SIMD16 that means that there can
be max 64 work-items per EU. With 8 EU per subslice this gives 512
work-items on a single subslice. For correct intra-WG synchronization
all its WIs must be executed on the same subslice (to access the same
SLM, where the synchronization primitives are stored). Thus, with SIMD16
and LargeGRF the work-group size must not exceed 512 (PVC example).
So far `maxWorkGroupSize` is taken solely from a DeviceInfo structure
both in `ModuleTranslationUnit::processUnpackedBinary()` and
`ModuleImp::initialize()`. This method does not take kernel parameters
(LargeGRF) into account. It allows to submit a kernel using LargeGRF
with SIMD16 with the work-group size set to 1024. That leads to a hang.
Fix the `.maxWorkGroupSize` computation so that it takes the kernel
parameters into consideration.
Add new (for discrete platforms >= XeHP) and adapt existing tests, fix
cosmetics by the way.
