Confirm edited/validated destination address (UI layer)

[rachelmcr]

We need to update WooShippingEditAddressViewModel to handle the edited/validated destination address that the merchant confirms they want to use for the shipping label:

• In remotelyValidateAddress(), update the onConfirm closure set for WooShippingNormalizeAddressViewModel to handle a confirmed destination address. (This is called when the merchant taps the "Confirm..." button on the Confirm Address screen.)
• Add a method to remotely update the confirmed destination address, using the new "Update destination address" endpoint.
• Add a closure to call when the remote update is completed, which passes the destination address back to the bottom sheet to display it as the "Ship From" address (and ensure the address is now shown as "verified").
