anv: fix Gfx9 fast clears on srgb formats
Only MCS surfaces are affected because SRGB format are not listed as
supporting CCS compression.
Fixes CTS test :
dEQP-VK.api.image_clearing.core.clear_color_attachment.single_layer.*_srgb_*sample_count_*
dEQP-VK.api.image_clearing.dedicated_allocation.clear_color_attachment.single_layer.*srgb*
This is similar to what we did in Iris in f8961ea0 ("iris: Disable
sRGB fast-clears for non-0/1 values").
