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().

When allocation is created and createResource is set we need to
remove resourceHandle instead of allocation handle list otherwise
in long running application (a lot of allocations) we will observe
memory leak.

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.
