Introduce RecipientData in ReceiveTlvs

Introduce RecipientData in ReceiveTlvs

1. New Enum for Enhanced Data Handling:
   - Introduced the `RecipientData` enum, which allows the node to include
     additional data along with the `reply_path` sent to the counterparty.
   - The node anticipates receiving this data back for further processing.

2. Variants in RecipientData:
   - The `RecipientData` enum includes two variants.
   - One of the variants, `OffersContext`, holds the `payment_id`
     of the associated Outbound BOLT12 Payment.

3. Future Usage:
   - This enum will be utilized in a subsequent commit to abandon outbound
     payments that have failed to complete for various reasons.
