[v6 07/12] drm/amd: Add preempt and restore callbacks to userq funcs

[Alexander.Deucher at amd.com]

From: Alex Deucher <alexander.deucher at amd.com>

Add two new function pointers to struct amdgpu_userq_funcs:
- preempt: To handle preemption of user mode queues
- restore: To restore preempted user mode queues

These callbacks will allow the driver to properly manage queue
preemption and restoration when needed, such as during context
switching or priority changes.
