feat(storage-browser): add custom actions

[calebpollman]

Description of changes

Add custom actions support for StorageBrowser

• loosen handler interfaces to improve custom action ergonomics
• add useHandler, useAction and useList hooks
• simplify useView
• integrate useAction and useList hooks in to StorageBrowser views
• refactor action config types

Usage:

import { ActionHandler, ActionViewConfig, createStorageBrowser } from '@aws-amplify/ui-react-storage';

type MyAction = ActionHandler<{ myOptionalData: string }, { myOptionalOutput: string }>
const myAction: MyAction =  () => {}

const myActionViewConfig: ActionViewConfig<MyAction, 'MyActionView'> = {}

const { useAction, StorageBrowser } = createStorageBrowser({ actions: { 
  // no view slot, just handler
  myAction,
  // with view slot
  myActionViewConfig
))

const MyActionView = () => {
  const [atomicState, atomicHandler] = useAction('myAction')

  const items = []
  const [batchState, batchHandler] = useAction('myAction', { items })
 
  return ( ... )
}

<StorageBrowser views={{ MyActionView }} />

listLocations is no longer a default action?

Should this be kept?

Not specific to this PR but we need to make sure we don't recommend this in our public doc

Non-blocking but I think this file is not used anywhere and can be cleared.

I think you're probably right. We can do that separately for sure
