doubly closes #14773 (rebase of #14878 onto v3)

This switches remote forms to use XHRs for uploading, which enables us to track upload progress for files!

<script>
  import { uploadForm } from './upload.remote';
</script>

<form {...uploadForm} enctype="multipart/form-data">
  <input {...uploadForm.fields.file.as('file')} />
  <p>Progress: {(uploadForm.fields.file.progress().percent * 100).toFixed(2)}%</p>
  <button>Upload</button>
</form>
