lib/thread: Make thread_run not block the current state
If a thread wants to block a state transition it can use
thread_run_until. Otherwise just let the thread run. `thread_join` can
be used to block on the thread. Boot states are also a ramstage concept.
If we want to use this API in any other stage, we need a way of starting
a thread without talking about stages.
BUG=b:179699789
TEST=verify thread_run no longer blocks the current state
