Rtl support on web

[MohammedFaragallah]

Is your feature request related to a problem? Please describe.
As far as i can tell I18nmanager is a mock only on web which leads to rnpaper thinking it's always ltr

Describe the solution you'd like
Add direction property to paper theme that the library uses internally defaults to
I18nmanager rtl but allow users to provide a different value when they need to

Would that be a good approach or am I missing something please let me know 🙏
