The code which registers thread contexts originally returned the ID that
it had chosen, and let the CPU actually set the ID in the object itself.
That opened a window where calling contextId() on the ThreadContext
would return the wrong answer.
Instead, we can just set the ID immediately after it's decided. This
also localizes that logic and removes plumbing for the ID between that
decision and where it's actually applied.
