Re-use the implementation of ZE_STRUCTURE_TYPE_EXTERNAL_MEMORY_IMPORT_FD.
With this PR and https://github.com/oneapi-src/unified-runtime/pull/1696,
Three sub-tests in SYCL bindless image vulkan_interop/sampled_images.cpp
are passing on DG2 linux.
Also enable OPAQUE_FD for EXTERNAL_MEMORY_EXPORT_DESC.

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().

If the input count is zero or is greater than the number of sub-allocations,
the driver shall update the value with the total number of sub-allocations.
If count is less than the number of sub-allocations available, then driver
shall only retrieve properties for that number of sub-allocations.

Unify `getIpcMemHandle()` and `getIpcMemHandles()` and fix the issue of
missing IPC handles registration while reducing copy-pasted code.
Also replace `boHandle` with `boHandleWrapper` to leverage `refCount`
properly and avoid double-free.

- Change the heap/pageSize used based on the size of the reservation
required and the device heaps available.
- Return the page size required based on the size requested by the user
for virtual reservation and the devices on the system.

allocation is valid for the heap and page size that is required.
