Complete the transition to Noto as the default font.

- Both Noto and Noto Sans CJK JP are now used as font fallbacks,
  allowing to cover a rather large range of characters. This also makes
  it possible to mix the two fonts easily.
- Remove VL-Gothic from packages and from AboutSystem
- Add Noto fonts to the dependencies of the Haiku package.

This provides a similar look for all languages as discussed on the
mailing list.
