Update AABB when Sprite component changes in calculate_bounds_2d()

[matthew-gries]

Objective

• Fixes Update Aabb on Sprite::custom_size changed. #10587, where the Aabb component of entities with Sprite and Handle<Image> components was not automatically updated when Sprite::custom_size changed.

Solution

• In the query for entities with Sprite components in calculate_bounds_2d, use the Changed filter to detect for Sprites that changed as well as sprites that do not have Aabb components. As noted in the issue, this will cause the Aabb to be recalculated when other fields of the Sprite component change, but calculating the Aabb for sprites is trivial.

---

Changelog

• Modified query for entities with Sprite components in calculate_bounds_2d, so that entities with Sprite components that changed will also have their AABB recalculated.
