chrome://profiler infrastructure uses base time types.

Previously, chrome://profiler avoided base::TimeTicks and
base::TimeDelta because they're 64 bits.

At this point, that appears to be premature optimization. Switch to
using the base time types.

This is required for using chrome://profiler's infrastructure for
building thread time UMA metrics.
