Perf was nice and flat after https://skia-review.googlesource.com/c/skia/+/83240
but there was a 4-5x slowdown on the benchmarks themselves,
indicating that perhaps we were running nanobench on the
LITTLE cores (now on powersave) instead of the big cores we
thought (which were recently scaled down).
This experiment will show us FOR CERTAIN that we are
running on core 0 or 1 which is at .6 max frequency.
We expect to see a speedup from the previous results.
This is leading to turning of CPUs we don't need
to make sure nanobench is running on the ones we expect.

They seem to be their own special cases for what
governors they support.

This scaling logic correctly accounts for some devices
which have multiple CPUs. Previously, we were scaling
the smaller of these CPUs, which likely had a negative
impact on nanobench, given nanobench was single threaded
and the CPUs weren't allowed to idle much (because we
set the CPU).
This CL sets those additional CPUs to powersave when we run
nanobench and then correctly scales down the beefier
CPU we want to run nanobench on.
For DM, we just run it in ondemand mode, which will
hopefully be "as fast as possible", but allow the CPU
governor to scale down if overheating becomes a problem.

It's causing a lot of sleep for being too hot. ThermalManager assumes
the trip points are static, when in fact, they are dynamic.
