Winansi: Drop pre-Vista workaround (#6109)

1edeb9a
(Win32: warn if the console font doesn't support Unicode,
2014-06-10) introduced both code to detect the current console font on
Windows Vista and newer and a fallback for older systems to detect the
default console font and issue a warning if that font doesn't support
unicode.

Since we haven't supported any Windows older than Vista in almost a
decade, we don't need to keep the workaround.

This more or less fell out of #6108, but didn't quite fit into that PR.

There are also some other version specific hacks and workarounds I
considered dropping, but decided against:

*
492f709
* I'm unsure if this regression has ever been fixed or just become the
new normal.
* #5042
* So far this hasn't been an issue on Windows 8.1, but officially Go
1.21 and newer only support Windows 10 and newer. So this might become a
problem at any point.
