Integrate TieredPriorityExecutor under flag.

* Change is guarded behind the new flag
  --experimental_use_priority_in_analysis.
* Adds a priority to DirtyBuildingState. The priority based on a
  combination of a node's depth and how many times it has been
  restarted. Previously, information about a node's priority would be lost
  on restart and guessed from children.
* Adds `hasLowFanout` attribute to `SkyKey`, defaulting to true, and set false
  for `ActionLookupKey`, which has been observed to have more than 10k
  dependencies.
