macOS Support

[Saadnajmi]

Hello, I'm the main maintainer for React Native macOS. I am interested in adding macOS support for this library, and wanted to start an issue to make sure this aligned with your vision for the repo. Basically two things would need to be done:

1. Add a test app with React Native Test App. This will help with maintaining the macOS test app because it simplifies down to a single pod file, I believe @okwasniewski was already thinking of doing the same for visionOS.

2. Update the sources for macOS. I looked at the repo and that diff doesn't look too hard. React Native macOS is largely compatible with React Native iOS code. A couple of places we need to call Appkit instead of UIKit mostly. I think Dawn should also compile for macOS so no issues there either :)

I am interested in submitting a PR, though it might be a while 😅

yes that sounds great. Adding the build for macOS shouldn't be a problem. And also adding an example app would be welcomed. I'm excited for this :)

Interestingly enough, there are already macOS binaries available at https://github.com/google/dawn/

@wcandillon Sorry, where are the binaries? I couldn't find them looking through the repo. I'm having trouble building dawn locally so I was seeing if I could just locally use some prebuilt binaries :)

here they are: https://github.com/google/dawn/actions/workflows/ci.yml
Ours are at https://github.com/wcandillon/react-native-webgpu/actions/workflows/build-dawn.yml

I like the PR you opened, let's make it happen :)
