src: save the performance milestone time origin in the AliasedArray 
Previously we cache the time origin for the milestones in the user
land, and refresh it at pre-execution. As result the time origin
gets serialized into the snapshot and is therefore not deterministic.
Now we store it in the milestone array as an internal value and
reset the milestones at serialization time instead of
deserialization time. This improves the determinism of the snapshot.

Drive-by: remove the unused MarkMilestone() binding.

perf_hooks: refactor perf_hooks for snapshot building 
- Move Performance and InternalPerformance to a new
  lib/internal/perf/performance.js
- Move now() getMilestoneTimestamp() into
  lib/internal/perf/utils.js
- Rename lib/internal/perf/perf.js to
  lib/internal/perf/performance_entry.js
- Refresh time origin at startup (this means the
  time origins could differ between snapshot building
  time and snapshot creation time)
