Enable checkout-summary.compact block to show a total value based on visible totalizers

[victorhmp]

What problem is this solving?

Currently, the value received by the totalizersToShow prop is only taken into account to toggle the visibility of each totalizer, but doesn't have any effect in the Total value shown in the minicart.v2. This can create weird behaviors, such as this one:

In this image, the Total is greater than Subtotal because it takes into account the Shipping price. But since Shipping is not in being shown to users, it might be confusing.

To avoid this, we're adding a new totalCalculation prop, that enables users to control whether or not the checkout-summary.compact should only take into account the visible totalizers to calculate the Total displayed to users.

Also, we'll refrain from showing the Shipping and taxes calculated at checkout. disclaimer if the Shipping totalizer is already taken into account to show the Total price.

How to test it?

1. Go to the [master workspace](Link goes here!) and add the Top Wood Clock product to the cart. The minicart.v2 should pop open, and you should see this at the bottom:

Notice that the Total is greater than the Subtotal. That's because there's a shipping cost being added. The problem here is that the client doesn't know that, and the disclaimer at the bottom is misleading in this case since the shipping cost is already being considered.

2. Go to this workspace and add the same product to the cart. Now you should see a summary that looks like this:

This is now the default behavior, and the shipping cost is not taken into account.

3. Now go to this workspace and add the same item to the cart. You should see a summary that looks like this:

In this case, the checkout-summary.compact block is configured as:

"checkout-summary.compact#minicart": {
    "children": ["summary-totalizers#minicart"],
    "props": {
      "totalizersToShow": ["Items", "Discounts", "Shipping"]
    }
  },
