Implement the jank monitor.

The jank monitor watches janks on the browser UI and IO thread
using content::responsiveness::MetricSource. The monitor watches task
and native event on a separate sequence (i.e. the "monitor thread").
When the monitor observes task or event running for longer than a
threshold, it notifies the user class about the start and stop of the
jank through the Observer interface.

Bug: 904785
Test: unit_tests: JankMonitorTest.*
