Tommi 6866dc7806 Reland "Make sure that "current" rtc::Thread instances are always current for TaskQueueBase."
This reverts commit 28685dc08c.

Reason for revert: Speculative reland after looking into downstream
failures. It's possible that carryover state from unrelated tests
running in parallel was causing failures.

Original change's description:
> Revert "Make sure that "current" rtc::Thread instances are always current for TaskQueueBase."
> 
> This reverts commit 46b3bc6c24.
> 
> Reason for revert: Speculative revert. Breaks downstream project

> Original change's description:
> > Make sure that "current" rtc::Thread instances are always current for TaskQueueBase.
> > 
> > This is a necessary part of fulfilling the TaskQueueBase
> > interface. If a thread does not register as the current TQ, yet offers
> > the TQ interface, TQ 'current' checks will not work as expected and
> > code that relies them (TaskQueueBase::Current() and IsCurrent())
> > will run in unexpected ways.
