The driver used to invalidate the vector cache for meta operations
but this has been removed and I think it should be restored to fix
a bunch of regressions on GFX8.
This probably needs to be cleaned up but this is a hotfix.
This fixes a bunch of regressions and flakes on GFX8 like
dEQP-VK.pipeline.multisample.sample_locations_ext.draw.color.samples_4.*.
Fixes: 8f8d72af55 ("radv: Use access helpers for flushing with meta operations.")
