- `useStoreCartItemQuantity` now receives the cartItem instead of the `cartItemKey` as an argument. I didn't notice in previous reviews how it's used in the context where we already have a cartItem so implementing this reduces complexity and makes the hook more precise for it's purpose.
- Add `backorders_allowed` to the CartItem schema for the API. This allows for client to have correct logic for maximum quantity when this value is true.
- Implement the above in the `CartLineItemRow` so that quantity picker is limited by the amount of stock remaining if that is available (`lowStockRemaining`) and the `backorders_allowed` is false.
- maximum quantity is currently hardcoded to a (filtered) value of `99` when other conditions don't apply (see related issue in woocommerce/woocommerce-blocks#1913)
* add typedefs for CartItem
* remove cartItem from StoreCartItem typedef
* Implement new typedef and fix defaults as well as returned object.
Now that `cartItem` is only used internally, the default set on the state only has to be the properties required internally in the hook.
* add typedefs for shared settings and implement typedef comments.
* change hook name
