Add HPOS compatibility for the `orders_by_type_query` filter box in the order listing screen

[a-danae]

Fixes #496

Description

• Display the "shop_order_subtype" filter dropdown when HPOS is enabled. We're using the HPOS-specific woocommerce_order_list_table_restrict_manage_orders action to hook the same functionality that WC_Subscriptions_Order::restrict_manage_subscriptions has.
• Filter the arguments passed to wc_get_orders() when a value from the dropdown is selected and HPOS is enabled. We're using the HPOS-specific woocommerce_{ order type }_list_table_prepare_items_query_args filter for this, to perform the same functionality that WC_Subscriptions_Order::orders_by_type_query() does.

How to test this PR

1. Go to WooCommerce -> Settings -> Advanced -> Features. /wp-admin/admin.php?page=wc-settings&tab=advanced&section=features
2. Under Experimental features, select "High performance order storage (new)", enable "Keep the posts and orders tables in sync (compatibility mode)", and save
3. Go to WooCommerce -> Orders. /wp-admin/admin.php?page=wc-orders
4. Confirm that the "shop_order_subtype" dropdown filter shows up next to "Filter by registered customer"
5. As a shopper, get the following if you don't have them already:
   • A subscription
   • A renewal for the subscription
   • A resubscribed subscription
   • An order with a non-subscription product
   • A switched subscription
6. Go to WooCommerce -> Orders
7. Filter by each option from the dropdown and confirm that the results match the filter. Because we're missing the "Subscription relationship" column, I used the results from when "WordPress post tables" is enabled instead of HPOS as a reference
