schedule: zephyr_domain: include domain block in ll time tracking 

Include the possible domain block time when measuring the time it takes
to complete one iteration of the low-latency scheduler thread loop. The
ll timer metrics are typically used for initial system debug and it can
be misleading when domain block events are not counted in reported
average/max numbers.

Change the timing code to start measurement immediately after
domain thread semaphore is taken.
