Turn off Immer setAutoFreeze -- issues with modifying immutable (readonly) state

[ccrowley96]

Describe the bug
Immer auto freeze is suppressing issues related to react state object refs that should be immutable and readonly being edited. This came up in @msnyder-msft's behavior form dirty state refactor. Bugs related to linked object refs being edited, when they were thought to be cloned came up.

In order to fix these issues, we'll need to remove setAutoFreeze(false); in StandalonePropertyInspector.state.ts. This throws errors when any immutable state passed through produce is edited elsewhere (likely many places in our code base).
