Ability to register multiple cart transforms for same app

[dev-prakhar]

Hey Team.

We are using Cart Transform for multiple functionalities and we are using Cart Transform metafields to store the settings.

Since we do not want to exceed the function's input limit, we want to separate the logic for cart transforms into multiple functions. However, right now, one app can only register one cart transform per shop. This is going to create a lot of messy code, maintaining all the logics within single function and we will be reaching the input limit faster.

It would be amazing if we could register multiple cart transform functions :-)
