Issue:
Bug: [FEATURE] Supporting processors token in Payments API



### Feature Description

During the transition phase of Hyperswitch, Merchant should be able to send the processor's token to Hyperswitch to process MIT transaction. This is because, Merchant will not have the card data to migrate from Processor to Hyperswitch. 

### Possible Implementation

**#Solution 1**
In payments create+confirm API, we will add new enum processor_token in type under recurring_details  to support connector data. We will start supporting Bambora’s and we will slowly adopt every connectors.

- This field will be a replaceable field for payment method id. Merchant can either pass payment_method_id or {recurring_details.data:{processor_payment_token: "value", connector:"BAMBORA"}}. Connector can be enum. 

- Based on this field, we will fork the main flow, which will skip the payment_method part and use this data given in the request. 

**Expected Flow:** 
- Merchant needs to create customer before calling this API. 
- Call Payments API

**Technical changes information:**
- Routing is not involved - (No changes)
- Customer related process can also be ignored. (No changes, as merchant creates customer before calling this API)
- Populate connector_mandate_id in `router_data` from the request, instead of fetching from database. 

**In V1 we can add if else to handle the flow, in v2, we will follow separate handler with the same route.** 

**Flow shall be in the following order,** 
- Get tracker (create+confirm)
- Get customer (create + confirm)
- Skip to call connector (create + confirm). 
- response handling (create + confirm )

## Description
<!-- Describe your changes in detail -->
During the transition phase of Hyperswitch, Merchant should be able to send the processor's token to Hyperswitch to process MIT transaction. This is because, Merchant will not have the card data to migrate from Processor to Hyperswitch.
The migration is here:

<!--
Provide links to the files with corresponding changes.

Following are the paths where you can find config files:
1. `config`
2. `crates/router/src/configs`
3. `loadtest/config`
-->


## Motivation and Context
<!--
Why is this change required? What problem does it solve?
If it fixes an open issue, please link to the issue here.

If you don't have an issue, we'd recommend starting with one first so the PR
can focus on the implementation (unless it is an obvious bug or documentation fix
that will have little conversation).
-->


## How did you test it?
<!--
Did you write an integration/unit/API test to verify the code changes?
Or did you test this change manually (provide relevant screenshots)?
-->
### The testing flows are as follows:
1. Create a Setup Mandate Payment.
2. Get the payment_method_id.
3. Get the connector_mandate_id from payment_method table in db (using pm_method_id) -> this is our payment_processor_token (PPT).
4. Now create a recurring_payment using the above ppt.

The curls for the same are as follows:
1. Create a Setup Mandate Payment.
