Implement TreeProcessor to solve some issues with running the suite

- execute beforeAll/afterAll once per suite instead of once per child
  when running focused specs/suites Fixes #773
- refuse to execute an order if it would cause a suite with a beforeAll
  or afterAll to be re-entered after leaving once
- report children of an xdescribe similarly to how they would be
  reported if they were themselves x'd out Fixes #774
- only process the tree once instead of figuring it out again at each
  level

[finishes #87545620]
Fixes #776
