Wojciech Tyczyński d03eb6ed02 chore: Simplify Apple detection (#8035) 
Our Apple device detection misdetects any Webkit-based STB as Apple, due
to looking only at vendor property. To mitigate it, we were excluding
another user agents, but maintenance of this is problematic.
This PR tries to change direction - an Apple device right now is a
device with Apple vendor AND with characteristics of MacOS or iOS.
