Add RenderViewHostTestHarness ctor for thread bundle

Add a new constructor for RenderViewHostTestHarness (and its derived
class ChromeRenderViewHostTestHarness) to include
ScopedTaskEnvironment parameters. This will allow the test harness
classes to use the ScopedTaskEnvironment's task runner for mock time
task runners, instead of instantiating a separate
TestMockTimeTaskRunner.

This CL also modifies the UserActivityManagerTest unit tests to leverage
this in-built ScopedTaskEnvironment and remove the mock time task
runner, and also makes the FakeSmartDimModel implementation utilize the
task runner for posting tasks, to better mimick real-world behaviour.

Bug: 893425,  914640 ,  917580 
Test: - Builds and boots, inference calls checked via logs on nocturne
      - All related unit tests still pass.

[Power: ML]: Remove remaining uses of TestMockTimeTaskRunner

ScopedTaskEnvironment is sufficient for the purposes of power/ml
unit tests, so remove usages of TestMockTimeTaskRunner. This also
removes need to support both TestMockTimeTaskRunner *and*
ScopedTaskEnvironment in FakeBookClock.

Bug:  917580 
Test: All related unit tests still pass.
