Remove TermWin's is_utf8 method.

Browse Source 
All implementations of it work by checking the line_codepage field in
the ucsdata structure that the terminal itself already has a pointer
to. Therefore, it's a totally unnecessary query function: the terminal
can check the same thing directly by inspecting that structure!

(In fact, it already _does_ do that, for the purpose of actually
deciding how to decode terminal output data. It only uses this query
function at all for the auxiliary purpose of inventing useful tty
modes to pass to the backend.)
