[Bookings] Add Yosemite models for booking info

[RafaelKayumov]

Part of: WOOMOB-1508

Description

This PR updates Yosemite layer to support storing extra info for bookings in the local storage. Changes include:

• Adds order info property for the readonly Booking model. This will be used for getting extra info to display on booking list items and booking detail screen.
• Adds new readonly models: BookingOrderInfo, BookingCustomerInfo, BookingPaymentInfo, BookingProductInfo matching the relative Core Data entities added in Bookings: Add new entities for booking info #16242.
• Updates ReadOnlyConvertible conformance for the models to convert order info for the readonly Booking model.
• Updates BookingStore to map data from the fetched orders to associated bookings.

In the next PR, the order info will be populated on the UI.

Testing steps

The new data is not used yet so just CI passing is sufficient.

Testing information

Added tests to confirm the new mapping logic.

I'm just wondering what these MARK notations do at the extensions? Are they used for code generation or something?

No, just for clarity I believe.
