Documention for RTL support for Widgets

[mrashad2017]

Dears,

We did some work and investigation in mirroring, and we have valuable feedback to help bidirectional-languages users with the support they need to mirror their pages easily & quickly.

The work we did will minimize any effort to do mirroring as we can support them with code details.

Appreciate your guide and help to add this documentation in the proper format and place, and may be after your review, so I think will provide good help for bidirectional-languages users.
