Created registerFaultHandler() and checkFaultHandlerFromPageFaultManager()
and removed registering sigaction() from the contructor of the
PageFaultManagerLinux class.
Added if statment to check the current pagefault handler is from the
pagefault manager. If not, register the pagefault handler of the current
pagefault manager on linux.
Refactored windows exception vector adding logic to
registerFaultHandler() and call upon the constructor of the
PageFaultManagerWindows, and make
checkFaultHandlerFromPageFaultManager() always return true for windows.

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.

Shared-allocations are currently migrated to GPU by the page-fault
manager when calling executeCommandLists. Allocations to migrate are
taken from the lists container. However, if a shared-allocation
has been made resident with zeContextMakeMemoryResident(), it is not
added to the list container, and hence it is not migrated to device.
So, add a container of resident allocations to the driver and migrate
them along with the other allocations.
