- 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.

After resolving NEO-7684 in turns out that `zeKernelGetProperties`
is still returning wrong value for `maxNumSubgroups` since it
did not take into account `LargeGRF & SIMD` limitation.

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.

Optimize zeKernelSetGroupSize by early returning success if group size
values have not changed since last function call.
Moved ImplicitArgs construction above setGroupSize call
in kernel initialization to prevent pImplicitArgs being nullptr
in calls in which we use cached group sizes and early return.

- printf used in kernel is printed on synchronize() call, if
hang is detected - printf buffer was not printed immediately but
only when Kernel was destroyed
- this change adds copying printf buffer with internal engine
(whenever available) right after hang detection on
CommandQueue::synchronize() call
