Make command bar arguments skippable, configure Extrude selection to be skippable (#1353)

* Make commands able to be configured as 'skippable'

* Make command machine able to skip arguments

* Add support for skippable selections, which are not known until within input component

* Update extrude command config to skippable

* Use defaultValue to seed initial arg values, not payload

* Remove unused `payload` command config prop

* Make skip and defaultValue types more exact

* Remove console logs

* fmt

* Revert type tightening, not worth the headache
