This commit aligns the programming of the privileged stack MPU guard with that of the default stack guard (i.e of supervisor threads). In particular: - the guard is programmed BELOW the address indicated in arch.priv_stack_start; it is, therefore, similar to the default guard that is programmed BELOW stack_info.start. An ASSERT is added to confirm that the guard is programmed inside the thread privilege stack area. - the stack fail check is updated accordningly - arch.priv_stack_start is adjusted in arch_userspace_enter(), to make sure we account for a (possible) guard requirement, that is, if building with CONFIG_MPU_STACK_GUARD=y.
