Remove the type parameter from check_visibility, and only invoke it once. (#16812)
Currently, `check_visibility` is parameterized over a query filter that specifies the type of potentially-visible object. This has the unfortunate side effect that we need a separate system, `mark_view_visibility_as_changed_if_necessary`, to trigger view visibility change detection. That system is quite slow because it must iterate sequentially over all entities in the scene. This PR moves the query filter from `check_visibility` to a new component, `VisibilityClass`. `VisibilityClass` stores a list of type IDs, each corresponding to one of the query filters we used to use. Because `check_visibility` is no longer specialized to the query filter at the type level, Bevy now only needs to invoke it once, leading to better performance as `check_visibility` can do change detection on the fly rather than delegating it to a separate system. This commit also has ergonomic improvements, as there's no need for applications that want to add their own custom renderable components to add specializations of the `check_visibility` system to the schedule. Instead, they only need to ensure that the `ViewVisibility` component is properly kept up to date. The recommended way to do this, and the way that's demonstrated in the `custom_phase_item` and `specialized_mesh_pipeline` examples, is to make `ViewVisibility` a required component and to add the type ID to it in a component add hook. This patch does this for `Mesh3d`, `Mesh2d`, `Sprite`, `Light`, and `Node`, which means that most app code doesn't need to change at all. Note that, although this patch has a large impact on the performance of visibility determination, it doesn't actually improve the end-to-end frame time of `many_cubes`. That's because the render world was already effectively hiding the latency from `mark_view_visibility_as_changed_if_necessary`. This patch is, however, necessary for *further* improvements to `many_cubes` performance. `many_cubes` trace before:  `many_cubes` trace after:  ## Migration Guide * `check_visibility` no longer takes a `QueryFilter`, and there's no need to add it manually to your app schedule anymore for custom rendering items. Instead, entities with custom renderable components should add the appropriate type IDs to `VisibilityClass`. See `custom_phase_item` for an example.
