Add basic support for watchos

[Ukalnins]

This still needs some testing on older macOS/iOS/Xcode versions, but created the PR to get some feedback.

This PR should allow:

• Detecting watchOS devices connected trough iPhone
• Listing installed bundles
• Uninstalling/Installing on said watchOS device
• Starting debugger and application on said watchOS device

Looks like starting AFC service on watchOS is not possible, so copying files there and back again is also not possible.

I think this looks good, leaving it up to @ivanhernandez13 to figure out what gets merged first. I think it makes sense to get this merged and follow with any needed fixes since it largely seems to work.

Thanks for the PR and sorry for the delay.

This change looks good to me as well, and works well from playing around with it using Xcode 12.4 + iOS 14.5 + watchOS 7.4. @Ukalnins do you want to merge this in now or is there some additional changed you'd like to do?

I have a very minor change I'd like to merge as well but can merge this in first if you'd like.

I would like to test that building on macOS-10.14 still works and iOS-10 also still works. Hadn't had the time unfortunately. I'll try to do it tomorrow and report back if I had any issues.

You are welcome to merge your change and not wait for this.

Looks like this PR does not break anything on Mojave nor iOS 10.x or tvOS, so I think this can be merged.
