Order newly tracked CSS properties by popularity within their group

[nicoburns]

Summary

Moves the entries added in #37 and #38 to their place by popularity within their group (Chrome Status day_percentage, the max across an entry's properties). This matches the page's "roughly ordered by popularity" convention. Existing entries keep their order: each new entry is inserted before the first existing entry that is less popular than it.

Examples:

• mask-type (3.8%) now comes before mask-mode (2.1%).
• scroll-margin (8.5%) now comes before scroll-padding (6.8%).
• webkit-text-stroke, paint-order and the other new Text entries now sit before text-decoration-inset (0%).
• column-fill/column-rule (1.8%) now come before column-span (0.9%).

Data-only change; the moved entries themselves are unchanged.
