drm/amdgpu/gfx12: Implement cleaner shader support for GFX12 hardware

Browse source

This patch adds support for the PACKET3_RUN_CLEANER_SHADER packet in the
gfx_v12_0 module. This packet is used to emit the cleaner shader, which
is used to clear GPU memory before it's reused, helping to prevent data
leakage between different processes.

Finally, the patch updates the ring function structures to include the
new gfx_v12_0_ring_emit_cleaner_shader function. This allows the
cleaner shader to be emitted as part of the ring's operations.
