Don't examine every entity when extracting SpriteSources. (#12957)

`ExtractComponentPlugin` doesn't check to make sure the component is
actually present unless it's in the `QueryFilter`. This meant we placed
it everywhere. This regressed performance on many examples, such as
`many_cubes`.

Fixes #12956.
