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.

If on clCreateProgramWithSource() call we detect a nGen dummy kernel usage,
then enforce fallback to the patchtokens format (only for this kernel).
Extend this logic to all platforms (previously - only for TGL/ICL).

Allow for use of device binary in ocloc concat. Previously only
AR files could be concatenated.
This feature only works for zebin with AOT Product Config note.

This commit adds support for decoding SHT_ZEBIN_GTPIN_INFO type
sections. For each section, passed data will be stored in kernel info
(for corresponding kernel).

This commit adds support for parsing SHT_NOBITS zebin's ELF sections

- 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.
