ReinUsesLisp cb08e5bdd2 texture_cache: Always prepare image views on render targets 
Images used as render targets were not being "prepared", causing
desynchronizations on the texture cache. Needs #6669 to avoid
performance regressions on certain cooking titles.

- Fixes black shadows on Age of Calamity.
