lib/xe_util: Add xe fast-copy helper
In Xe2 and beyond fast-copy between objects with different pat indices
is quite common operation. Add fast-copy helper which requires only
src/dst bo handle, region, pat index and size of operation.
It is however limited to size being multiple of 4KiB and lesser or equal
16MiB but this limitation may removed if there will be user of this.
