Integrate with Google Analytics

[nerrad]

Currently Google Analytics (WooCommerce core option) integrates with the Cart and Checkout flow to trigger events for GA. We need to ensure that purchases through the cart and checkout block flow triggers the appropriate events (and any related extensibility points are available for those trigger points).

As much as possible split up the work into independent chunks, for now use this as a tracking issue.

Current Events:

• listing_impression (ec:addImpression) - woocommerce_after_shop_loop_item
• listing_click (ec:setAction click) - woocommerce_after_shop_loop_item
• add_transaction (ec:setAction purchase) - is_order_received_page()
• remove_from_cart (ec:setAction remove) - woocommerce_after_cart
• product_detail (ec:setAction detail) - woocommerce_after_single_product
• checkout_process (ec:setAction checkout) - woocommerce_after_checkout_form
• add to cart (ec:setAction add) - woocommerce_after_add_to_cart_button

As a minimum we need to emit on:

• Add to Cart
• Remove from cart/update cart item
• When rendering a product
• Clicking an product link
• On Checkout

Blocks still uses the order received page so add_transaction is covered. If we use a block in the future we'll need a new event.

Analytics Pro Events That Intersect with Blocks:

Note some of these use server side hooks which the API still uses, so won't all need a JS event.

• selected_payment_method
• placed_order
• started_payment
• completed_purchase
• applied_coupon
• removed_coupon
• estimated_shipping
• product_impression

Product impression data:

• id
• title
• "list type" uses the current query. We could use block name here.
