patch 9.1.0030: Cannot use terminal alternate font
Problem: Cannot use terminal alternate fonts (PMunch)
Solution: Support terminal alternate fonts using
CSI SGR 10-20 and t_CF code (PMunch)
Add support for alternate font highlighting
This adds support for alternate font highlighting using CSI SGR 10-20.
Few terminals currently support this, but with added tool support this
should improve over time. The change here is more or less taken from how
colors are configured and applied, but there might be some parts I
missed while implementing it. Changing fonts is done through the new
`:hi ctermfont` attribute which takes a number, 0 is the normal font, and
the numbers 1-9 select an "alternative" font. Which fonts are in use is
up to the terminal.
