While working on debugging the motion vectors, I noticed the code will fail to work if MSAA is enabled in the viewport. This error also happens when trying to view the normal roughness buffer when MSAA is enabled.
Since the debug effects do not support sampling from Multisampled textures directly, and this is the only use case where these methods are called, the most effective solution is to only ever return the resolved versions of the textures, which are ready by the time the debug effects are drawn.
This issue is not a regression from any particular change as far as I can tell.
Fixes #62955.
