drm/amdgpu/gfx11: Add Cleaner Shader Support for GFX11.5 GPUs

Browse Source 
Enable the cleaner shader for GFX11.5.0/11.5.1 GPUs to provide data
isolation between GPU workloads. The cleaner shader is responsible for
clearing the Local Data Store (LDS), Vector General Purpose Registers
(VGPRs), and Scalar General Purpose Registers (SGPRs), which helps
prevent data leakage and ensures accurate computation results.

This update extends cleaner shader support to GFX11.5.0/11.5.1 GPUs,
previously available for GFX11.0.3. It enhances security by clearing GPU
memory between processes and maintains a consistent GPU state across KGD
and KFD workloads.
