Issue:
Bug: [BUG] customers endpoints refactoring in the Stripe Compatibility Layer



### Bug Description

There are a couple of mismatches and missing fields in the `/customers` endpoints in the Stripe Compatibility Layer. The corresponding match logic and structs/enums should be added to prevent the flow from breaking.

Pull request description:
## Type of Change
<!-- Put an `x` in the boxes that apply -->

- [x] Bugfix
- [x] Refactoring

## Description
<!-- Describe your changes in detail -->
Address of a new customer was being accepted as a `SecretSerdeValue` in the `CustomerCreate` and `CustomerUpdate` requests. This PR does the following : 

- Add a new struct `AddressDetails` in the `customers` flow for the `address` field.
- Add the `address` field in Stripe Compatibility Layer and the corresponding mappings for it.
- Add missing fields in `CustomerCreate` and `CustomerUpdate` requests as per Stripe API reference.

## 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 its 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)?
-->
Manually

## Checklist
<!-- Put an `x` in the boxes that apply -->

- [x] I formatted the code `cargo +nightly fmt --all`
- [x] I addressed lints thrown by `cargo clippy`
- [x] I reviewed submitted code

Testing:

Manually
