drm/amdgpu: fix vulkan test performance drop and hang on VI

caused by not program dynamic_cu_mask_addr in the KIQ MQD.

v2: create struct vi_mqd_allocation in FB which will contain
1. PM4 MQD structure.
2. Write Pointer Poll Memory.
3. Read Pointer Report Memory
4. Dynamic CU Mask.
5. Dynamic RB Mask.
