Enable lazy load for the Investigations part of the create page

Incident create shows Incident and Investigation sections so
both can be created at once. Set the lower Investigation section
to lazy load since it will always load below the fold. It will
then load the components only when the user scrolls down. This
reduces the burst of requests from the Incident create page by
half on the initial load.
