Add daemon task startup hook / timer task creation consistency check (#1009)

Add daemon task startup hook / timer task creation consistency check (#1009)

Add a compile time check that emits a helpful error message if the user
attempts to create a daemon task startup hook without also creating the
timer/daemon task.

The timer/daemon task startup hook runs in the context of the timer/daemon
task.  Therefore, it won't run even if configUSE_DAEMON_TASK_STARTUP_HOOK
is set to 1 if the timer task isn't created.  The timer task is only created if
configUSE_TIMERS is not equal to 0.
