Allow to set custom autocomplete values on password mdui-textfield

[swagliquido]

Currently if I use this element, autocomplete gets turned off:
<mdui-text-field type="password" autocomplete="new-password"></mdui-text-field>

The pull request removes the limitation. I tested it and now it works for me. I don't know why there was this check in the code:

autocomplete=${ifDefined(
  this.type === 'password' ? 'off' : this.autocomplete,
)}

I just changed it to this:
autocomplete=${this.autocomplete}

You are right, but please revert the unrelated formatting changes.
