Adds ReaderTypography (replaces ReaderHyphenation) (#6072)

Browse Source 
Replace Hyphenation menu with Typography menu.
This works mostly like before:
- typography/hyphenation is chosen according to the book
  metadata language,
- one can set a default or a fallback language,
- hyphenation is now just a subset of typography, and
  can be disabled while still setting a language and
  enabling the other features,
- the typography language enables newly added features
  to crengine: per-language line breaking rules and
  per-language Harfbuzz glyph selection.
