feat: admin upload controls (#11615)

### What?
Adds the ability to add additional components to the file upload
component.

```ts
export const Media: CollectionConfig = {
  slug: 'media',
  upload: {
    admin: {
      components: {
        controls: [
          '/collections/components/Control/index.js#UploadControl',
        ],
      },
    },
  },
  fields: [],
}
```

### Provider
Use the `useUploadControls` provider to either `setUploadControlFile`
passing a file object, or set the file by url using
`setUploadControlFileUrl`.

```tsx
'use client'
import { Button, useUploadControls } from '@payloadcms/ui'
import React, { useCallback } from 'react'

export const UploadControl = () => {
  const { setUploadControlFile, setUploadControlFileUrl } = useUploadControls()

  const loadFromFile = useCallback(async () => {
    const response = await fetch('https://payloadcms.com/images/universal-truth.jpg')
    const blob = await response.blob()
    const file = new File([blob], 'universal-truth.jpg', { type: 'image/jpeg' })
    setUploadControlFile(file)
  }, [setUploadControlFile])

  const loadFromUrl = useCallback(() => {
    setUploadControlFileUrl('https://payloadcms.com/images/universal-truth.jpg')
  }, [setUploadControlFileUrl])

  return (
    <div>
      <Button id="load-from-file-upload-button" onClick={loadFromFile}>
        Load from File
      </Button>
      <br />
      <Button id="load-from-url-upload-button" onClick={loadFromUrl}>
        Load from URL
      </Button>
    </div>
  )
}
```


### Why?
Add the ability to use a custom component to select a document to
upload.
