- Properly check for IPC event handle flag to determine if the event
pool memory is sharable between processes.
- Given Host Visible Event Pool, a check is done to determine if the
Host memory can be shared between the processes.
- Enabled handling if Event Host Memory is shareable for DRM
- If Event Pool Memory is Not shareable, then retrieving the IPC Event
Pool Handle returns unsupported.

Define single .clang-tidy configuration with all used checks and use
NOLINT to selectively silence tool. That way cleanup should be easier.
third_part/ has its own configuration that disables clang-tidy for this

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

- In WSL the handle for DMA buf is an NT handle.
- To share and import this memory we check if the
handle is an NT handle before attempting to
load as an FD.
- If the handle is and NT handle, then we open the fd
as an NT handle.

to determine if Linux + WDDM memory manager is in use.

zeMemGetAllocProperties() specifies an ID for the allocation can be
retrieved by the application. This can be used by applications to
identify the allocation throughout the application lifetime.
We were currently returning as id the same allocation address. This
patch fixes it to return a true unique identifier for the allocation.
