fix(router): add config to avoid connector tokenization for apple pay simplified flow

[ShankarSinghC]

Type of Change

• Bugfix
• New feature
• Enhancement
• Refactoring
• Dependency updates
• Documentation
• CI/CD

Description

Currently tokenization flow for a connector can be decide based on the payment method type. Now as there are two different flows (manual and simplified) for apple pay we need to consider this as well while decide the type of tokenization. This changes is required because some connectors follow connector tokenization for manual apple pay flow and network tokenization for simplified apple pay flow.

To handle this an config (apple_pay_pre_decrypt_flow) is been added which can be set to network_tokenization or connector_tokenization according to the connector.

Additional Changes

• This PR modifies the API contract
• This PR modifies the database schema
• This PR modifies application configuration/environment variables

Motivation and Context

How did you test it?

-> Connector create for manual flow

-> Apple pay payment create for manual flow

-> Connector create for simplified flow

-> Apple pay payment create for simplified flow

-> Verified the payment status in connector dashboard

-> Google pay payment create for Stripe

-> Google pay payment create for Checkout

Test case :-
As this pr contains tokenization changes different tokenization flow needs to be tested. Also wallet payments needs to be tested.
For apple pay both the flows needs to be tested (manual and simplified)
