drm/amdgpu/gfx10: Add Cleaner Shader Support for GFX10.3.x GPUs

Browse Source 
Enable the cleaner shader for other GFX10.3.x series of 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.x 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.
