Update legacy CBI markup to use actual table, tr, th and td elements
instead of using div element corresponding table classes.
Fixes compatibility with OpenWrt 2020 theme.

The `data-type` attribute is used to bind datatype validators to a widget
while some templates used the same attribute to denote the name of the
underlying widget.
Change the `data-type` attributes referring to the widget name to
`data-widget` in order to stop the JS token error spam.
