Handle mismatching texture size with copy dependencies (#4364)

* Handle mismatching texture size with copy dependencies

* Create copy and render textures with the minimum possible size

* Only align width for comparisons, assume that height is always exact

* Fix IsExactMatch size check

* Allow sampler and copy textures to match textures with larger width

* Delete texture ChangeSize related code

* Move AdjustSize to TextureInfo and give it a better name, adjust usages

* Fix GetMinimumWidthInGob when minimumWidth > width

* Only update render targets that are actually cleared for clear

Avoids creating textures with incorrect sizes

* Delete UpdateRenderTargetState method that is not needed anymore

Clears now only ever sets the render targets that will be cleared rather than all of them
