Reviewed by Tim Nguyen.

Creates a feature flag for the margin-trim CSS property and also
adds it to the CSS parser behind this flag. When the flag is enabled the
property can be set according to the grammar in the spec.

This property has the following grammar:
none | block | inline | [ block-start || inline-start || block-end || inline-end ]
