UI: always use international font

This means Blender can display more text correctly without having to enable
user interface translation. Previously the quality of the font was lower,
but that has been fixed now.

The font files have now been ungzipped, which results in faster file loading
as Freetype can read only the parts of the file that it needs. Blender download
size should not increase since the release package is compressed.

This includes improvements for Cyrillic characters from the latest DejaVu
Sans fonts from D6960, contributed by Harley Acheson. Fixes T74097.
