[native] introduce tag farcaster button

Summary:
This diff introduces the button + onPress logic for tagging a farcaster channel. The onPress logic will dispatch the createOrUpdateFarcasterChannelTagAction that was introduced in previous diffs

Please note this diff will not be landed until I introduce a gate to guarantee no one can trigger this button

Depends on D11785

Test Plan:
Confirmed that when I pressed the bottom I was able to call the create_or_update_farcaster_channel_tag endpoint

Also please see the demo video below to see the ui/ux button
