Bigint timestamps and durations: Pt1

- Switched to using bigints to store things like Timestamps and
Durations loaded from trace processor.
- Created a new HighPrecisionTime class which is used where sub-ns
precision is required such as the visible time window.
- Track controllers and renderers still use numbers for now, these
shall be addressed in Pt2.
- This CL indirectly fixes b/175110985 due to a re-write of the overview
timeline panel renderer.
