Removed test-only methods from CastRunner, WebContentRunner and
CastComponent that were previously used in
cast_runner_integration_tests.

1. Removed CastRunner and WebContentRunner constructors that take
web.Context. Now context is always created in WebContentRunner.
2. Removed test-only methods.
3. Updated TestComponentContext to allow initialization with all
services cloned from /svc.

The tests now inject a script into the frame in order to test
functionality that was previously tested with the test-only methods.

Previous attempt to land this CL was reverted due to flake in
CastRunnerIntegrationTest.CanRecreateContext test. The test kills
WebEngine and was waiting Component termination and assumed that
Context and ContextProvider were torn down as well, but they may
be destroyed with some delay. To fix this issue this version of the
CL adds explicit wait for Context destruction and removes
ContextProvider caching from WebContentRunner.
