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

This change introduces checking of the return value
of wait function in case of blocking version of
evictUnusedAllocations(). Furthermore, it propagates
the error to the callers. It contains also ULTs.

There is no need to force 2MB alignment for CPU allocation in dual
storage usage. Additionaly for WSL this will allow to avoid usage of
malloc in driver path.

When making graphics allocations resident in multi-GPU scenarios,
we should make them resident only if there's an allocation for that
device. So return appropriate null pointer and skip it.

Add a per-instance SVMAllocsManager::nonGpuDomainAllocs container for
all allocations to be removed in
moveAllocationsWithinUMAllocsManagerToGpuDomain. This approach replaces
the current iterative search and performs the task faster.
Add 7 new unit-tests to verify the functionality related to
nonGpuDomainAllocs container, both in expected and unexpected/synthetic
scenarios.
For UTs replace a dummy unifiedMemoryManager pointer with a pointer to
an instace of SVMAllocsManager, otherwise a SegFault error is thrown at
the end of tests.
Perform overall cleanup in related tests implementation, includes but
not limited to removal of:
- givenInitialPlacementGpu\
WhenMovingToGpuDomainThenFirstAccessDoesNotInvokeTransfer
As it is fully covered by:
givenAllocationMovedToGpuDomain\
WhenVerifyingPagefaultThenAllocationIsMovedToCpuDomain
- givenInitialPlacementGpu\
WhenVerifyingPagefaultThenFirstAccessDoesNotInvokeTransfer
As it is fully covered by:
givenTbxAndnitialPlacementGpu\
WhenVerifyingPagefaultThenMemoryIsUnprotectedOnly
Finally, reduce code duplication where possible.
