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().

With this commit on DG2 32bit driver will check if passed host ptr for
clEnqueueReadBuffer is write combined memory. If check will be true copy
will be make on CPU.

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.

Dont pin and instantiate buffer objects associated with a USM
allocation for device >0 at allocation time, but instead, just
do a USERPTR ioctl, as with the allocation associated with
device 0.
