[NoCheck] Avoid pointers in EventAggregatorMgr

- Removes 2 CHECK calls
- Makes AggregateStore/EventAggregator move-assignable (so they no
  longer need to be pointers)
  - Adds move constructor for ProtectedFields.
- Creates 'NotNullUniquePtr' and 'PinnedUniquePtr' that guarantees that
  the held object can never be nullptr.
  - Used for steady_clock_ which must be a pointer, but should never be
    null.
