Add missing widgets to incidents for parity with issues

What does this MR do and why?

Contributes to Ensure incidents and Service Desk issues use le... (#502823 - closed)

We plan to use the new work item flow also for incidents and so all currently available widgets for issues also need to be available for incidents. Incidents will continue to use the legacy detail views then because we didn't widgetize all functionality of the incidents detail view yet.

So this MR adds missing widgets to incidents for parity with issues

It also adds the ability to handle widget_options to the widgets migration helper. (but we removed the weight widget that has widget_options from this MR)
