Enable profiler timing with a field trial.
In Browser process, if profiler timing field trial is "Enabled", enable profiler timing.
This is necessary to measure the performance impact of enabling profiler timing on Android, and, perhaps, rolling out profiler timing enabling afterwards.
Profiler timing is currently disabled on Android because of performance concerns, but the impact on the standard perf metricts is not yet known, hence this CL.
