Macos take2

draft because i need to get a todo list together.

Adds macos as a target for our ios runtime! Also adds a macos target for our example (which is a different app completely, very minimalistic right now).

macos, macos rosetta, macos (designed for ipad), and ios  all co existing in peace, from the same runtime project

![CleanShot 2023-05-17 at 18 32 04@2x](https://github.com/rive-app/rive/assets/1216025/eead319d-a16b-4098-a7db-d5f033b1ef8f)

todo:
- [x] update build scripts to build supporting macos (gotta do this)
- [x] run formatter
- [x] test out builds in forked version of ios? (gotta do this)
- [ ] one more stab at catalyst? (i think we can try that later...)
- [ ] do we need a more comprehensive example setup for macos (I think we can do this later & try to pull zach's examples in)
- [ ] I think we should restructure the ios project, but i think we can do that after this as well (i just think the folder structure/project structure can do with some work, now that we add macos (and should make room for tvos as well)
- [x] probably got tests to fix
- [ ] there's probably a bunch of looking at errors in the debugger and figuring those out, but i would hope that we can deploy with some warnings here too.

catalyst problem:

we get this error:
and the problem is basically that we can target a specific library for macos, but we need one for macos and one for macos catalyst. they share the same architecture, so i dont think we can lipo them into one file...

we could change the compiled binaries before creating the frameworks I guess though? .. maybe something to try..

`/Users/maxwelltalbot/development/rive/rive/packages/runtime_ios/dependencies/debug/librive_skia_renderer_macos.a(cg_factory.o), building for Mac Catalyst, but linking in object file built for macOS, file '/Users/maxwelltalbot/development/rive/rive/packages/runtime_ios/dependencies/debug/librive_skia_renderer_macos.a' for architecture arm64` basically
