This reverts commit 475006d4a3.
Reason for revert: Speculative revert. Breaks downstream project
Original change's description:
> Revert back to using the task_queue_ for guarding access.
>
> This removes the SequenceChecker that was temporarily used while
> the rtc::Thread TQ implementation was being fixed.
>
> Bug: none
