Remove casts to integers for texture and EFB formats

The only remaining casts for these types that I know of are in TextureInfo (where format_name is set to the int version of the format, and since that affects filenames and probably would break resource packs, I'm not changing it) and in TextureDecoder_Common's TexDecoder_DrawOverlay, which will be handled separately.
