rescaling_pass: Fix rescaling Color2DArray ImageFetch offsets
ImageFetch offsets for 2D array coordinates have a different composite size than the coordinates. The rescaling pass was not taking this into account.
Fixes broken shaders when scaling is enabled in Astral Chain, and likely other titles.
