Memory accesses can get corrupted when there's a disagreement between: * the aux-mode of existing cache lines for a surface and * the aux-usage in that surface's RENDER_SURFACE_STATE object We have already prevented hardware from seeing this conflict for rendering operations, but due to how the L3 is shared among multiple clients in gfx12 (e.g., sampler engine, render engine, etc.), we need to expand the scope of the existing solution. Now, before any access of a compressible resource, we make sure to flush the prior aux-mode from the caches. The majority of changes here refactor things for use in a new function, flush_previous_aux_mode. The remaining change calls that function from within iris_resource_prepare_access.
