[com_menus] Hide Process button when in Trashed status (Admin menu)

PR for #15134

This PR will ensure that the Process button is hidden (I have no idea why you cant batch process trashed items and that is beyond the scope of this PR)

### Steps to reproduce the issue
Create an Administrator menu.
Create a menu item in this Administrator menu.
Trash this menu item.
Click `Search Tools` button.
Select `Trashed` in `- Select Status -` dropdown.
Select the Administrator menu in `- Select Menu -` dropdown.
Click `Select All` checkbox.
Click `Batch` button.

### Expected result
Cancel button only.

### Actual result
