Timings that should remain real-time even under MOCK_TIME are now
explicitly using subtle::TimeTicksNowIgnoringOverride().

ThreadPoolClock defaults to DefaultTickClock in this CL but will be
overridden under ScopedTaskEnvironment's upcoming multi-threaded
MOCK_TIME mode @
https://chromium-review.googlesource.com/c/chromium/src/+/1686776

Ultimately, when MOCK_TIME mode always mocks TimeTicks::Now(), we will
be able to remove this and use TimeTicks::Now() again directly for
these calls.

Bonus #1: Gets rid of a call to DeprecatedGetMockTickClock().

Bonus #2: Added thread annotations to DelayedTaskManager::queue_lock_.
