Optional PRIVILEGED_DATA wrapper + Partner-Supported-Ports submodule update (#1433)

Browse source 
- Instead, when MPU wrappers are not used, allow port to override
  PRIVILEGED_FUNCTION, PRIVILEGED_DATA, or FREERTOS_SYSTEM_CALL
  selectively, permitting custom section placement at link-time.
- Allows critical data to be placed in port-specific location for
  improved performance, notably for cache-coherent SMP.
- Does not require enabling the full MPU wrappers.
