vim: Improve HiDPI experience with a better font

GUI Vim defaults to Fixedsys, a raster font which does not scale. On
HiDPI displays, Vim is unusable in its default configuration despite
supporting HiDPI generally. This issue was never solved upstream, and
the official Vim builds still have this poor experience. For w64dk, I
want a better out-of-the-box experience. It tries Consolas, present on
any HiDPI system, and then falls back to Fixedsys if necessary (XP). As
a side effect, the unicode experience improves as well because Fixedsys
has little support beyond ASCII.

There's an argument to be made for Lucida Console, but Consolas edges
out by not having a space in the name. This also "breaks the seal" on
making other changes to Vim's generally poor defaults, perhaps to adopt
some of neovim's more thoughtful defaults:
