Message:

Editor: Format and sanitize font family names according the CSS spec.

This fixes two bugs in the font library.

• Fonts using special characters were not being rendered properly in the frontend.
• Allows the ability to use generic() in font family names.

Props mmaattiiaass, nithins53, kafleg, vivekawsm, swissspidy, audrasjb.
Fixes #60537.
