(Feature Request) Make autoInit return the initialized components

[blikblum]

Feature Request

Return the components initialized by a call to autoInit

Motivation

Currently, when integrating mdc with a framework or with custom elements is necessary to individually create the components, store its references and destroy when appropriate. With autoInit is possible to accomplish the first step with one call (create the components) but will not provide the means to destroy the component instances

Use case

By autoInit returning the initialized components we could write components like the below which will initialize (and) finalize all mdc components with auto-init attribute

class MDAutoComponent extends HTMLElement {
  connectedCallback() {
    this.mdcComponents = mdc.autoInit(this)
  }
  disconnectedCallback() {
    this.mdcComponents.forEach((comp) => comp.destroy())
  }
}

Seems reasonable. Is this something you would like to change and make a pull request for?
