Added lockMemory in context to explicitly locking memory,
Added a boolean flag in graphics_allocation to indicate the allocation
is locked, and modified memory_operations_handler to add lock().

Change the logic to work correctly with makeResident() when lock() is
called previously for the same memory region

- Create a new IPC Memory handle upon call to getIpcMemHandle if the
previous handle has been freed.
- Release the Ipc Memory Handle when zeMemPutIpcHandle is called.
- Create a new IPC Handle for tracking thru zeMemGetAllocProperties
when ze_external_memory_export_fd_t is used.
- Convert FD to opaque IPC handle and IPC Handle to FD.

The size of this type is at least 64 bytes due to
ZE_MAX_IPC_HANDLE_SIZE. This change introduces usage
of const reference instead of copying.

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
folder.

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.
