Disable timing from chrome://profiler on Android.
On Android, on a arm CPU, TimeTicks::Now() is taking 900ns (20 times
what it takes on a desktop x86 CPU). The bigger user of TimeTicks::Now()
is tracked_objects::TrackedTime, and this impacts the overall
performance of Chrome on this platform.
This CL adds compile line flags that allows to disable
tracked_objects::TrackedTime. It also disable
tracked_objects::TrackedTime by default on Android.
