Also delete font.MultiFace. We can resurrect a font.MultiFace type if we
need it in the future, but for now, it's simpler if it lives in the
plan9font package.

Package font defines an interface for font faces.
Other packages provide font face implementations. For example, a
truetype package (not part of this CL) would provide one based on .ttf
font files.
This CL also introduces the golang.org/x/exp/shiny/font/plan9font
package, a concrete implementation of the font.Face interface for the
Plan 9 bitmap font format.
