[css-fonts] Allow UA to not download font hints if it would have ignored them #3926
Description
@zachleat proposed a uses-hints media query in order to have different @font-face rules (URLs really) to fonts with and without hinting data - which can be up to 50% of the file size, but is ignored on most systems (iOS, Android, Chrome)
