Support custom user form modes.

I'm going to make a new version of this patch for the 2.0.x branch.

Please review MR !6, which supports custom user form modes on RoleAssign 2.0.x.

It identifies user form modes by checking the base form id. If the base form is the user form, then the form id is added to the $user_forms array:

if (($form_state->getBuildInfo()['base_form_id']) == 'user_form') {
      $user_forms[] = $form_id;
    }

I then made the user forms code the default case on the switch() statement.

Looks good to me. Thanks for the MR!
