html: Parse a comma-separated list of faces in the <font> tag (#32622)

Browse source 
This change parses a comma-separated list of faces in the `<font>` tag
and also moves the parsing code from `stylo` to Servo. This means that
the servo-specific code can be removed from stylo decreasing the
differences between Gecko and Servo's version of `stylo`.
