Use IntersectsVolume for breakout example collisions

[rparrett]

Objective

Fixes #11479

Solution

• Remove collide_aabb.rs
• Re-implement the example-specific collision code in the example, taking advantage of the new IntersectsVolume trait.

Changelog

• Removed sprite::collide_aabb::collide and sprite::collide_aabb::Collision.

Migration Guide

sprite::collide_aabb::collide and sprite::collide_aabb::Collision were removed.

// Before
let collision = bevy::sprite::collide_aabb::collide(a_pos, a_size, b_pos, b_size);
if collision.is_some() {
    // ...
}

// After
let collision = Aabb2d::new(a_pos.truncate(), a_size / 2.)
    .intersects(&Aabb2d::new(b_pos.truncate(), b_size / 2.));
if collision {
    // ...
}

If you were making use collide_aabb::Collision, see the new collide_with_side function in the breakout example.

Discussion

As discussed in the linked issue, maybe we want to wait on bevy_sprite generally making use of Aabb2b so users don't need to construct it manually. But since they do need to construct the bounding circle for the ball manually, this doesn't seem like a big deal to me.

Looks pretty good to me! A couple of simple comments on the collision function could be nice especially since this is an example, but it's quite understandable either way so it's non-blocking
