drm/amdgpu/gfx11: Add Cleaner Shader Support for GFX11.5.4

Browse Source 
The Cleaner Shader is responsible for clearing LDS, VGPRs and SGPRs
between GPU workloads to enforce process isolation and avoid data
leakage.

The cleaner shader clears per-wave GPU state (LDS, VGPRs and SGPRs)
between workloads, improving process isolation and preventing stale data
from being observed by subsequent tasks.

This reuses the existing cleaner shader used on GFX11.0.3 and enables it
for GFX11.5.4 GPUs when firmware requirements are met.
