FreeType: address font license issues (#5230)

It appears we were shipping font files without license text, and I
had my doubts about the bitmap fonts being usable directly.

This replaces existing TTF fonts with Apache-2.0 licensed fonts from
chome core (Cousine, Arimo, Tinos). Include the full license file
for all three fonts.

The Lucida Sans font bitmap is removed entirely for non-freetype
builds. There is therefore only mono fonts for non-freetype builds.
