Integrate ECE for Payment Processing in the Blocks Checkout Page

[rafaelzaleski]

Implement the Stripe Express Checkout Element (ECE) to process payments on the WooCommerce Blocks checkout page. This task involves integrating ECE in a way that it handles payment transactions during the checkout process.

Expected Behavior:

• ECE successfully processes payments on the WooCommerce Blocks checkout page without disrupting the existing checkout flow.
• It's not expected for the ECE checkout to function in any other flows or within the shortcode checkout.

Tasks:

• Integrate ECE with WooCommerce Blocks
• Implement Payment Processing Logic
