[Feature request] run-ios supports mac catalyst target

[robertying]

Describe the Feature

Mac Catalyst has already been available for React Native projects since 0.62-rc.

Now I believe we can only build the app using Xcode. Running react-native run-ios with --device flag does not work, since CLI cannot find any iOS devices.

It would be great if CLI can start to accept Mac device names, such as My Mac or the device's name, so we can use command line to invoke the build process.

Possible Implementations

Update CLI to allow Mac as the target device.

I may be able to look into this and create a pull request when free.

Great idea. I believe it has to do with the way we get devices from the underlying Xcode script. I haven't looked at it yet, but my idea would be to check whether it returns Mac devices and if not, whether we can pass it a flag to do so. Alternatively, just get Mac devices the other way as a fallback.
