Deprecate SpriteSheetBundle and AtlasImageBundle (bevyengine#12218)

# Objective

After the `TextureAtlas` changes that landed in 0.13,
`SpriteSheetBundle` is equivalent to `TextureAtlas` + `SpriteBundle` and
`AtlasImageBundle` is equivalent to `TextureAtlas` + `ImageBundle`. As
such, the atlas bundles aren't particularly useful / necessary additions
to the API anymore.

In addition, atlas bundles are inconsistent with `ImageScaleMode` (also
introduced in 0.13) which doesn't have its own version of each image
bundle.

## Solution

Deprecate `SpriteSheetBundle` and `AtlasImageBundle` in favor of
including `TextureAtlas` as a separate component alongside
`SpriteBundle` and `ImageBundle`, respectively.

---

## Changelog

- Deprecated `SpriteSheetBundle` and `AtlasImageBundle`.

## Migration Guide

- `SpriteSheetBundle` has been deprecated. Use `TextureAtlas` alongside
a `SpriteBundle` instead.
- `AtlasImageBundle` has been deprecated. Use `TextureAtlas` alongside
an `ImageBundle` instead.
