[Nearby] Reland: Add onboarding to receive dialog

Fixed the debug test failure by removing contact manager all together
from the onboarding page test since it was not actually needed in the
fist place.

PS1 has the original
PS2 has the fix


> [Nearby] Add onboarding to receive dialog
>
> This converts the onboarding and visibility pages to use the
> nearby-template-page and hosts them in receive dialog. If the user
> attempts to enter high visibility mode and nearby is not enabled, we
> force onboarding to be run first.
>
> Screenshot of onboarding running from settings:
