Rollforward of cl/211538380: Add a $waitAndVerify() function

NEW: Assign goog.getUid to a local private const var in Set, preventing the global mocking behavior of some tests from impacting Set.

RELNOTES: Add a $waitAndVerify() function to MockInterface and a $waitAndVerifyAll() function to MockControl that returns a goog.Promise that resolves when expectations have been registered.

Automated g4 rollback of changelist 211629440.

*** Reason for rollback ***

Rollforward by not allowing goog.getUid to be mocked for Set.

Set the type of getInjectedData to {?}.

Reasons:
1) It isn't statically verifiable. Even if you cast the result, it may not be true, as the injected data may change depending on server setup. Thus, you aren't protected from runtime errors so this isn't valuable for type checking.

2) It's not an API we can easily fix. We had to do cr/202516164 to fix local, but there are tons of users of this API.

Add a 1/2 second delay to allow the inappropriate synchronous test to…

… work even though it should be async.

The test should be fixed to be async. The current 1/2 sec delay in the infrastructure will be removed soon and the test will fail without custom delay code.
