LTR/RTL hook

Some of the components can have complexities with LTR/RTL using only CSS. It would require additional changes to Javascript code. So it can be useful to have Paragon hook for LTR/RTL directions.

@monteri I believe this relates to what we talked about in our Paragon<>RG sync last week. When you get a chance, do you mind expanding on the issue description to include more specifics about the proposed contribution (i.e., more details about the problem and proposed solution)?
