Settings Synchronization: Apple Pay / Google Pay

[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 Apple Pay / Google Pay configuration settings to existing methods that check for Apple Pay / Google Pay enabled/disabled. 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 Apple Pay / Google Pay settings from the WC Stripe Apple Pay / Google Pay settings.

For example, this payment request method should be updated to use the Stripe configuration we added in #3916.

Acceptance criteria

• Merchants should be able to toggle settings from Stripe Apple Pay / Google Pay settings and we should see those changes in the WooCommerce Stripe Gateway Apple Pay / Google Pay settings.
• Merchants should be able to toggle settings from WC stripe Apple Pay / Google Pay settings, and we should see those changes in the Stripe dashboard Apple Pay / Google Pay settings.
