doc: Improve build speed, disable doc's widgets build

Building the widget_preview_xxx programs takes a while and should
be required only when rebuilding the doc. Arguably breaking something
in elm may break only the widget-preview build but I believe this is
a rare case.

This speeds up a regular elm build by >20s on my machine.
