drm/amdgpu/gfx10: Enable cleaner shader for GFX10.3.2/10.3.4/10.3.5 GPUs

Browse Source 
Enable the cleaner shader for GFX10.3.2/10.3.4/10.3.5 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 GFX10.3.2/10.3.4/10.3.5
GPUs, previously available for GFX10.3.0. It enhances security by
clearing GPU memory between processes and maintains a consistent GPU
state across KGD and KFD workloads.
