Fastlane - Block checkout static meta comment is missing (3757)

[stracker-phil]

Description

This PR moves the feature-detection code into a separate hook that is always fired on checkout, cart and shop pages.

Before this PR, the flag was only output if AXO was eligible, the cart did not contain a subscription and the session was not in continuation mode:

woocommerce-paypal-payments/modules/ppcp-axo/src/AxoModule.php

Lines 197 to 203 in 7d0504e

	if ( ! $is_paypal_enabled
	|| ! $c->get( 'axo.eligible' )
	|| $this->is_paypal_continuation()
	|| $subscription_helper->cart_contains_subscription()
	) {
	return;
	}

So this will fire each time ACDC and Fastlane are enabled, right?
