[presentation-api] Define that "TV" should appear as token for UA-string when presentation API is used to render on TV

sicking has just created a new issue for 
https://github.com/w3c/presentation-api:

== Define that "TV" should appear as token for UA-string when 
presentation API is used to render on TV ==
Mozilla's experience is that the few websites that today target TVs 
require that a "TV" token is included in the UA string in order for 
the website to render an appropriate TV UI.

I think this is something that's worth getting into a specification as
 quickly as we can, in order to prevent the mess that we currently 
have on mobile. The problem on mobile was that originally there was no
 token to indicate "mobile device", which lead to websites solving the
 problem with perpetually out-of-date databases, harder for new 
players to enter the space, etc.

At the very least, we should define that when implementing that 1-UA 
mode, the implementation should use a UA string apporpriate for the 
target device. So if using 1-UA mode to stream to a TV, the "hidden 
iframe" running on the controller device, should use a UA-string 
appropriate for TVs.

But I think it would also be good to include an informative note that 
when implementing the presentation-side of the presentation API on a 
TV, to include a "TV" token in the UA-string.
