[msbuild] Provide the correct value for the operating system for tvOS and watchOS to a few tasks. Fixes #6200. (#7226)

The problem with #6200 was that we'd pass -mios-version-min=x.y to the metal
tool even for tvOS apps. This fixes it so that now pass -mtvos-version-min.

Fixes https://github.com/xamarin/xamarin-macios/issues/6200.
