Separate Metrics into "load" and "build" domains.

Provide a way to record two different sets of metrics.
This will be useful for persistent mode, where the "load"
metrics will stay the same on each invocation, while
the "build" metrics will be reset and recomputed on
each incremental build invocation.

+ Add a new "dependency scan" metric which measures
  the time it takes to traverse the build graph
  to determine which commands need to run, before
  building anything.
