fuchsia: Update for zx_task_suspend() supporting processes

zx_task_suspend() now supports suspending processes. This is somewhat
more reliable than suspending the constituent threads because after the
call returns and the token is being held, any subsequently started
threads will start in the the suspended state.

However, because the suspend is asynchronous the threads of the process
still need to be iterated to wait for them to assert ZX_THREAD_SUSPENDED
(and that can and does still fail to happen for a number of reasons). So
while improved, this class is still only best-effort.

Additionally, as the version of ScopedTaskSuspend that took a thread
wasn't being used, remove that.
