We already found out that rayon is causing some grief (very high overhead of the way threads are woken up, dependency inversion issues), and we suspect it might be causing more (keeping worker threads alive longer than they should, translating to never leaving high power state).
We need a way to easily compare between with/without multithreading via rayon when diagnosing various issues.

We need a way to switch it on and off to compare the performance and power usage of various test cases.
The new pref is "webrender.wnable-multithreading" and does not require a restart.
