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.
