Move GA4 implementation for blocks within the extension

[mikkamp]

User story

The WooCommerce Blocks extension has a separate implementation for supporting tracking events from Blocks, see: woocommerce/woocommerce-blocks#3953
This code is also present within WooCommerce core as part of the blocks package.

Now that this has matured, we shouldn't have to maintain the code for this in a separate location. So it's best to move this code within the Google Analytics Integration extension.

Potential blockers/points to take into consideration

• Original blocking issue: Analytics Scripts should use the WordPress Scripts API #186
• Implementation is in TypeScript whereas this extension is still using jQuery
• Triggers are still tied to an experimental hook, this can be promoted within WC Blocks if needed.

Describe the solution you'd like

For all the Google Analytics tracking code to be maintained in the same extension

Technical

A good example to get references from is how the hooks are used with GLA to add additional tracking: https://github.com/woocommerce/google-listings-and-ads/blob/2.1.2/js/src/gtag-events/index.js
