userspace: Move selected variables to userspace-accessible memory partition

Relocate specific variables to a memory partition accessible from userspace
to enable running the system agent in userspace. This change ensures that
only the required structures is accessible for userspace modules,
while privileged data remains in kernel-only memory.
