Bug
1550804 - Add color scheme simulation to the inspector. r=pbro
This adds a color scheme simulation toggle button in the rules view,
which will toggle between 4 different states: default, dark, light,
and no-preference.
This feature is currently hidden away under a preference:
devtools.inspector.color-scheme-simulation.enabled
The final UI/UX still needs to be figured out, however, this initial step is
to land the ability to prototype this feature.
