For #7661: Add variant-specific schemas for deep links

In order to target specific variants of Fenix, we're adding schemas that
are specific that app in order to avoid collisions with the other
variants and with other forks of fenix that may have the same schemas.

The current schema for variants:
 - Fenix Nightly: `fenix-nightly://`
 - Fenix Beta: `fenix-beta://`
 - Everything else: `fenix://`
