Dualcpu: Set mailbox message owner in NS mailbox queue slot
NSPE mailbox sets the task handle into the owner field of the
queue slot.
After the PSA Client result is returned, the task handle can be
fetched from the owner filed and the waiting task can be woken
up according to the handle value.
Declare tfm_ns_mailbox_get_task_handle() to fetch the handle of
current NS task executing the mailbox functionalities.
Implement a dummy tfm_ns_mailbox_get_task_handle() which returns
NULL when sleep/wake-up mechanism is not required.
