Implement onboarding for P3A on Android (original) (raw)

Description

The follow up issue for #6176 . It is required to implement notification about P3A during onboarding as it is done for desktop.

For existing users, show the P3A checkbox modal on next app launch:

The P3A checkbox modal takes priority over any other modals that might be in queue (for example, set Brave as default browser).
