Settings Synchronization: Hook up payment methods configuration

[hsingyuc]

We aim to allow merchants to update gateway settings from both WC Stripe settings and Stripe dashboard settings.

In #3916 we are fetching the payment method configuration settings. For this issue, we want to hook up enabled payment methods(admin settings) to payment method configurations. After we are able to toggle settings from Stripe, and see those changes in the WooCommerce Stripe settings, we also want to be able to update the Stripe dashboard configuration settings from the WC Stripe settings.

udpate_enabled_payment_methods should be updated to use the Stripe configuration we added in #3916.

Acceptance criteria

• Merchants should be able to toggle payment gateway settings from Stripe dashboard settings and we should see those changes in the WooCommerce Stripe settings.
• Merchants should be able to toggle payment gateway settings from WC Stripe settings, and we should see those changes in the Stripe dashboard settings.

Notes

• Blocked by Settings Synchronization : Fetch Stripe settings with Stripe configuration API #3916
• Create a PR based on the feature branch
• Update payment method configuration
