Introduce the managing_system privilege for components like the platform_driver to allow it to call system management functionality that is reserved by kernel or special firmware, e.g., ARM Trusted Firmware. The former RAM resource configuration attribute `constrain_phys`, which enabled to constrain the region of physical RAM to be used, gets replaced by the new, broader managing_system configuration attribute of a `start` node. It gets enforced by the sandbox library. Ref #3816
