- Relaxed the Virtual Memory Reservation to allow pStart and not fail if
the pStart value is not obtained.
- Moves checks on pStart to the user to check and determine if they want
to re-reserve or use the address allocated.
- Changed reserveGpuAddress to use unit64_t type to allow internal
address range structure assignment without cast.

- Enabled allocation of specified base address in the targeted heap.
- Enabled virtual memory reservations to grow by allocating at the start
of the heap vs the end of the heap.

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.

Add a clearQueueTillFirstFailure interface to DeferredDeleter, which
iterates the queue from the front and delete the allocations in the
queue till a failure. It is called by defer deletion of allocations
occupied by mutliple contexts to unlock the execution in main thread

If a handle cannot be obtained, like PRIME_HANDLE_TO_FD, then
properly check for the error and propagate it upwards.

This change extends the logic of opening IPC
memory handles and fills the gap between this
logic and allocation of USM device buffers.
When HEAP_EXTENDED is available, then it is
preferred.

This change replaces unneeded copying of std::vectors
with usage of const references. Furthermore, it adds
reserve() call before filling the container via push_back().
