commit 6a60f01228557982e6508c5919cc21fcfddf110b

[fuchsia] Implement browser tests for WebRunner Context service.

Tests may interact with the WebRunner FIDL services and the underlying
browser objects for end to end testing of service and browser
functionality.

* Add a browser test launcher main() for WebRunner.
* Add some simple navigation tests.
* Wire up GoBack()/GoForward() FIDL calls.
* Add embedded test server resources and initialization logic.
* Add missing deletion & notification calls to BrowserContext dtor.
* Use FIDL events for navigation state changes.

* Bug fixes:
  ** Move BrowserContext and Screen deletion to PostMainMessageLoopRun(),
     so that they may use the MessageLoop during teardown.
  ** Fix Frame dtor to allow for null WindowTreeHosts (headless case)
  ** Fix std::move logic in Frame ctor which lead to no WebContents
     observer being registered.

[fuchsia] Add webrunner unit tests, browsertests to Fuchsia bots.

* Fixed webrunner_unittests (tests were not being exercised, so the
  test code drifted from the impl)
* Added webrunner_unittests, webrunner_browsertests to Fuchsia test
  bot list.

[fuchsia] Refactor browsertests into Context and Frame specific suites.

context_impl_browsertest.cc was running the risk of becoming a large
catch-all for all browsertests.

This CL breaks the existing tests into Context- and Frame-specific
suites, which should be a more manageable structure going forward.
