accel/ivpu: Remove copy engine support

Browse Source 
Copy engine was deprecated by the FW and is no longer supported.
Compute engine includes all copy engine functionality and should be used
instead.

This change does not affect user space as the copy engine was never
used outside of a couple of tests.
