1. stylo: make font-variant-* longhands parsing more tolerant. …

   Avoid early returning Err() in parsers, so we could let the the caller
   of the parsers to handle the rest of input, and return error if it requires
   parsing entirely.
   
   The point is let returning Err() stay inside input.try(), so we can count
   on input.try() to restore the position when parsing invalid idents.

2. stylo: support font-variant shorthand. …

   We still count on Bug 1356124 to fix font-variant-alternates longhand, so we
   can get font-variant shorthand work properly.
   
   Some comments about Bug 1356124 have been removed, since this shorthand code
   should just work once we fix Bug 1356124.
