This change introduces "is APF enabled" system properties, and
uses them as trigger conditions for APF nodes / pre-APF nodes.
By default APF nodes are active, and pre-APF nodes are inactive,
which maintains the situation before this change.
A future experiment will flip "is APF enabled" system properties,
deactivating APF nodes and activating pre-APF nodes. For more
info see go/pixel-perf-apf-experiment.

By default slow it down as auto margins can lead to faster ramping up in
low activity use cases.
Set it back to default in GAME mode to retain previous behavior. Set it
explicitly for DISPLAY_IDLE as a potential area for more tuning in the
future.

And reduce DownRateLimitUs to 500us as the system should be more
reactive now when something needs to rampup quickly.
Enable pertask iowait boost too as with auto dvfs headroom enabled all
tasks will start form 0 util_avg and this could impact iowait tasks
without this being enabled to help them migrate up to bigger cores.
Camera use cases should still use their own default DownRateLimitUs and
disable this feature to keep their dvfs_headroom tuning intact.

This CL defines CAMERA_MULTICAM_BOOST (with the same settings as the
existing CAMERA_ZOOMING_BOOST). Having both definitions is necessary to
be able to transition from zooming boost to multicam boost. Once the
multicam boost flag is fully rolled out, we can remove the
CAMERA_ZOOMING_BOOST.

Since the system is more reactive now when tasks are getting busier, set
DownRateLimitUs to 500us to avoid increasing power.
Also enable pertask iowait boost as util_avg will always start from
0 for forked tasks and this could impact io tasks that need additional
help to ensure to migrate to bigger core if they need more perf.

It's disabled by default.
Ensure camera and game mode explicitly disable it too as it is only
required when auto margins are enabled for now.
Ensure it is disabled when screen is off too as We don't want io

Reducing CPUDVFSHeadroom can help save power in 60fps and 240fps

(ag/27725456), we can see savings without any impact to framedrop rate.
