Reland "[Nearby] Add dummy nearby-confirmation-page component"

This is a reland of 5563bea3
Reverted in crrev.com/c/2276045 for failing on the linux-blink-cors-rel
bots. Fixed by adding 'network::features::kOutOfBlinkCors' to the
enabled list in featureList().

Original change's description:
> [Nearby] Add dummy nearby-confirmation-page component
>
> This component will contain a confirmation screen when sending to
> strangers that are not in the local contacts. The component is empty
> right now and will be populated in upcoming CLs.
