Nested artboard types: node, leaf, layout

~~Adding as a draft to start testing.~~

- [x] Add node, leaf, and layout types.
- [x] Leaf supports fit and alignment.
- [x] Leaf alignment is floating point instead of enum allowing for animation later.
- [x] Layout allows external hosting artboards to take the nested layout node and host it in another hierarchy.
- [x] Measure and control size for NestedArtboard from native.
- [x] FFI changes for external layout node
- [x] WASM changes for external layout node.
- [x] Move layouts to RiveNative.

~~For a follow up PR:
I think it's time to move some of rive_common into rive_native. I think the layout stuff would be a good start. @philter take a look at how the rive_binding.cpp is shared in rive_native for both FFI and WASM. I think it would simplify our layout bindings to use this model too.~~
Nevermind, we need it for this PR or ```LayoutNode.fromExternal``` doesn't work.
