Revert "Fix UI corruption for AMD gpus with Vulkan (#9169)" (#9237)

# Objective

Fixes https://github.com/bevyengine/bevy/issues/9234

re-breaks: The issues that were linked in #9169 

## Solution

Revert the PR that broke tonemapping/postprocessing/etc.

Any passes that are post msaa resolve need to use the main textures, not
the msaa texture.

## Changelog

Idk what to put here since it's a revert.
