Merge #867

867: Implement methods on Rect2 and Aabb r=Bromeon a=parasyte

The docs are based on the Godot documentation for these types, and the code is based on the C++ that implements them.

Only documented methods are implemented here. This is especially notable for the `Aabb` type, which has many methods in C++ which are not documented for GDScript.

I also took some liberties with a few method names and types. For instance, `Rect2::grow_margin` takes an enum argument, and `Aabb::get_endpoint` returns `Option<Vector3>`. These are different from the GDScript counterparts. `Aabb::get_area` was renamed to `Aabb::get_volume`, etc.

Finally, I haven't added any tests for `Aabb` because I did that file last and got bored/lazy before writing any tests (this is what happens when you are not adamant about TDD). The `Rect2` tests did help find plenty of minor bugs, so it is worthwhile to test `Aabb`.

Closes #864
