TaskQueueBase: Add PostDelayedHighPrecisionTask().

As per go/postdelayedtask-precision-in-webrtc we want to reduce the
precision of PostDelayedTask() in order to schedule work on the CPU
more efficiently. In order not to break "high precision" use cases, a
new API is added to allow opting in to high precision.

PostDelayedHighPrecisionTask() has the same precision that
PostDelayedTask() has today, but by changing the interface's
requirements on PostDelayedTask(), adding the high precision version
of it will unblock making the old PostDelayedTask() API lower
precision.

This CL does not update implementations to support low precision so
until those are updated, both PostDelayedTask() and
PostDelayedHighPrecisionTask() have the same precision (=high).

This CL also adds TODOs to make some rtc::Thread-specific versions
of PostTask/PostDelayedTask obsolete, see
https://crbug.com/webrtc/13582 for more info.
