Rasterizer refactor hotfixes (#6465)

* texture_codec: Clamp buffer end to tiled buffer size

* Fixes crash on Pokemon Super Mystery Dungeon

* rasterizer_cache: Use rect for duplicate surface

* Fixes broken bloom in fire emblem

* surface_params: Check levels for exact match

* It was removed previously to prevent copies when games used the base level of a multi level surface. FE on the other hand will first use the base level and then use it as a face of a cubemap with many levels. So instead check if the surface equal or more levels and consider it an exact match in that case

* gl_texture_runtime: Bind old tex to 2D target

* Fixes a small error opengl would print when creating texture cubes

* gl_blit_helper: Fix nearest filter

* Use texture unit 2 which has the nearest sampler bound
