Michel Weststrate 25158416ce Freeze incoming data ...

Summary:
This diff will enabling freezing (making immutable) of all data we receive from the device. This prevents dev mistakes causing components not to update or logic being hard to reason about. Also this makes Immer's `produce` faster in the typical case

Since this is potentially a risky change, that might break existing plugin logic, it has been put behind a GK https://www.internalfb.com/intern/gatekeeper/projects/flipper_frozen_data/

I did some quick exploratory testing on all plugins available for Facebook iOS / Android, and the only plugin that caused trouble was Fresco, which is fixed in this diff as well.
