- Added support for mapping any portion of a virtual allocation to a
physical mapping with a lookup function for reserved virtual addresses.
- Added support for multiple mappings linked to the same virtual
reservation.
- Fixed bug with 64 bit addresses on windows with invalid addresses
passed to the user.

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

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().

Discarding RAII lock returned from function almost always
is a bug. This change introduces usage of [[no_discard]]
attribute from C++17 to prevent such misues.

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

- Add getMemoryManagerType to check which memory manager has been init
to determine if Linux + WDDM memory manager is in use.
- Add isNTHandle to test and verify if a handle is an NT handle during
L0 Open IPC Handle.

Move out neoDevice dependent pieces of memory manager code into
separate methods. Those methods could be used for recreating a neoDevice
after a device reset is performed.
