drm/amdgpu/gfx9: Add cleaner shader support for GFX9.4.4 hardware

This commit extends the cleaner shader feature to support GFX9.4.4
hardware.

The cleaner shader feature is used to clear or initialize certain GPU
resources, such as Local Data Share (LDS), Vector General Purpose
Registers (VGPRs), and Scalar General Purpose Registers (SGPRs). This
operation needs to be performed in isolation, while no other tasks
should be running on the GPU at the same time.

Previously, the cleaner shader feature was implemented for GFX9.4.3
hardware. This commit adds support for GFX9.4.4 hardware by allowing the
cleaner shader to be used with this hardware version.
