luci-base: switch from server side to client side widget markup

Do not render standard widgets like checkboxes, select boxes,
text input fields etc. on the server side anymore but utilize
the ui.js primitives instead.

This avoids logic duplication between server side cbi templates
and JS widgets in the future.
