Stop using near-suspended assertion on Mac

Reviewed by Chris Dumez.
In 272937@main we stopped using the near-suspended process state on iOS so that
background processes
suspended more promptly. However, we held off on doing that on the Mac because
it caused a
regression in PLT5.
In this patch, we now stop using the near-suspended state on Mac as well. To
fix the benchmark
regression, we preserve the old behavior of allowing cached processes to run in
the background for
30 seconds after they enter the process cache by explicitly taking a background
activity when the
process enters the cache.
