[native] introduce tag channel by name option in action sheet

Summary:
This diff introduces removes all the unnecessary UI elements and introduces a new "Other" option in the action sheet. When the user presses on the"Other" option they will be navigated to the TagFarcasterChannelByName screen

If the user presses on a channel name then a farcaster channel tag will be created with that channel

The UI will continue to be updated + improved in a subsequent diff

Depends on D11893

Test Plan:
Confirmed that a farcaster channel tag was created if a channel name was selected:

EDIT: here is a screenshot with the updated /CHANNEL_ID format:
