As the first step in implementing ARM v8M's security extension:
  * add a new feature bit ARM_FEATURE_M_SECURITY
  * add the CPU state field that indicates whether the CPU is
    currently in the secure state
  * add a migration subsection for this new state
    (we will add the Secure copies of banked register state
    to this subsection in later patches)
  * add a #define for the one new-in-v8M exception type
  * make the CPU debug log print S/NS status
