Summary:
Ref T13249. Ref T13258. In some cases, builds are not idempotent and should not be restarted casually.
If the scary part is at the very end (deploy / provision / whatever), it could be okay to restart them if they previously failed.
Also, make the "reasons why you can't restart" and "explanations of why you can't restart" logic a little more cohesive.
Test Plan:
- Tried to restart builds in various states (failed/not failed, restartable always/if failed/never, already restarted), got appropriate errors or restarts.
- (I'm not sure the "Autoplan" error is normally reachable, since you can't edit autoplans to configure things to let you try to restart them.)

Summary: Ref T5936. This implements build implementations aborting early when the build has since been restarted. Build steps now periodically poll to see if the build's current generation does not match their generation, and they throw a `HarbormasterBuildAbortedException` if that is the case.
Test Plan: Tested locally on my machine with the sleep build step.

Summary: We've received feedback that the "core - exception" is incredibly confusing, to the point where developers see this and write off the build failure as a Phabricator error that is unrelated to their changes.
Test Plan: Ran a build with a `exit 1` run step, didn't see the "core - exception" appear.
