- Properly check for IPC event handle flag to determine if the event
pool memory is sharable between processes.
- Given Host Visible Event Pool, a check is done to determine if the
Host memory can be shared between the processes.
- Enabled handling if Event Host Memory is shareable for DRM
- If Event Pool Memory is Not shareable, then retrieving the IPC Event
Pool Handle returns unsupported.

This commit fixes problem with untransfered shared usm memory to gpu
when there is submit to gpu trigerred by user event. Also there is a fix
for dead lock problem caused by mixed orders of locking mutexes in csr
and in direct submission controller.

With flag enabled, when app calls freeSVMAlloc on device usm allocation,
don't free it immediately but save it,
and try to use it on subsequent allocations.
This allocation cache will be trimmed if an allocation fails.

Use enum class for MemoryPool in GraphicsAllocation
This change will ensure that GA is constructed in the proper way
- Rename namespace for isSystemMemoryPool method
- Add method getMemoryPoolString for logging actual pool which is in used
- Remove wrong pattern in GraphicsAllocation constructor

Define single .clang-tidy configuration with all used checks and use
NOLINT to selectively silence tool. That way cleanup should be easier.
third_part/ has its own configuration that disables clang-tidy for this
folder.

When using implicit scaling, device allocations may have
more than one internal allocation created internally. In that case,
a separate dma-buf handle per internal allocation needs to be
exported.
So introduced two driver experimental extensions to export and
import more than one IPC handle:
- zexMemGetIpcHandles
- zexMemOpenIpcHandles
