feat(POM-419): Dynamic Checkout lifecycle events

[vitalii-vanziak-cko]

Description

Refactored:

1. Added val original: PODynamicCheckoutPaymentMethod to all internal PaymentMethod interactor types. It is needed for lifecycle events and make it easy to access the original type without the need to lookup for it.
2. Changed DynamicCheckoutInteractorState to keep the whole PaymentMethod object instead of only IDs for the following states (allows to avoid lookup for the object by id and simplifies the logic):
   selectedPaymentMethodId -> selectedPaymentMethod
   processingPaymentMethodId -> processingPaymentMethod
   pendingSubmitPaymentMethodId -> pendingSubmitPaymentMethod
3. Refactored startup concurrency to send lifecycle events at correct moment.
4. Extracted some methods for readability.

Added:

1. PODynamicCheckoutEvent and sending all lifecycle events.
2. PODynamicCheckoutDelegate dispatching preferredScheme (for card) and defaultValues (for nAPM).
3. Added PODynamicCheckoutPaymentMethod.Display.description, it used as text for customer token payment types (card and APM) with fallback to display.name when null.
4. logAttributes but not used yet, logs will be added in separate PR.
