Core: Thread mode transition from NS to S
Change TF-M Core to require NS client to make secure
function requests in thread mode instead of handler
mode.
Different secure API options of DEPRIORITIZE and
SVCCLEAR are obsolete, remove them.
Clear registers on secure function entry to avoid
leaking data.
Set AIRCR.PRIS flag by default to avoid NS pre-emption
of secure fault handler and SVC handlers.
