Bump min OS versions to what Xcode 14 supports. Fixes xamarin#15216.

Bump min OS versions to:

* iOS 11.0
* tvOS 11.0
* watchOS 4.0 (not really relevant for .NET, but matches iOS 11.0)
* macOS 10.15

Also bump the min version to execute our tooling to the macOS min version (it
doesn't make sense to be able to run our tooling on an OS you can't run the
compiled results on).

Fixes xamarin#15216.
