Spec: https://drafts.csswg.org/css-logical-1/#box
Implement margin-{block,inline}-{start,end}, padding-{block,inline}-{start,end} and
border-{block,inline}-{start,end}-{width,style,color}
using the standard names (currently they're already supported using
-webkit prefix and slightly different names).
Only longhands properties would be implemented as part of this,
the shorthands are not supported yet prefixed so they're left for a different issue.
The full list of properties would be: margin-block-start, margin-block-end,
margin-inline-start, margin-inline-end, padding-block-start, padding-block-end,
padding-inline-start, padding-inline-end, border-block-start-width, border-block-end-width,
border-inline-start-width, border-inline-end-width, border-block-start-style,
border-block-end-style, border-inline-start-style, border-inline-end-style,
border-block-start-color, border-block-end-color, border-inline-start-color,
border-inline-end-color.
