[PATCH i-g-t v2 3/3] lib/amdgpu: Add encrypted flag for secure user queues

When creating secure user queues, set the
AMDGPU_GEM_CREATE_ENCRYPTED flag for the GTT allocation if the
queue context is marked as secure. This ensures proper memory
protection for secure command submissions through user queues.
