[Masonry] Introduce parsing for masonry-template-tracks

1. Introducing the masonry-template-tracks property, which currently
   replicates the behavior of grid-template-[column|rows].

   This change reuses most of grid's parsing and serialization code.
   However, this will be refactored later to match the definitions in
   https://tabatkins.github.io/specs/css-masonry/#template-tracks.

2. Adding web tests to cover parsing for the new property.
