Can't disable selectize for `type: select`

[drzraf]

I'm using some Grav fields within another widget manager on the admin-side. I found that selectize binding may sometimes be annoying and would like to disable it. But I couldn't find a way to do this.

• templates/forms/fields/select/select.html.twig forcefully creates the data-grav-selectize attribute.
• <admin-plugin>/themes/grav/app/forms/fields/selectize.js forcefull SelectizeField any DOM node having the above attribute (whatever it's value is)
