Correctly integrate StoragePartition into TestingProfile.

Until this CL, TestingProfile had 3 distinct URLRequestContexts it would return to the user: one via profile->GetDefaultStoragePartition()->GetRequestContext(), one via profile->GetRequestContext(), and one via profile->GetResourceContext->GetRequestContext().  All of these had different cookie stores.  This CL unified them so they all return the one from profile->GetDefaultStoragePartition()->GetRequestContext(). This correctly mimics how production code works.

Doing this had a bunch of implications:
 (1) Removes TestingProfile::CreateRequestContext()/ResetRequestContext()
 (2) Changes MockRequestContext to share the URLRequestContext with TestingProfile.
 (3) TestingProfile now requires all BrowserThreads.

Point (3) effectively adds TestBrowserThreadBundle into a bunch more spots. Because of that, we also have the following changes:
  (a) AshTestBase now has a TestBrowserThreadBundle
  (b) Removed a bunch of real threads from tests.
  (c) TemplateUrlService has reworked synchronization semantics.
  (d) Removed MultiThreadTestHelper.
  (e) Added TestingIOThread class + testing API in IOThread to mock out various IO thread tasks which enervated with the new TestBrowserThreadBundle.
