Add the RISC-V privileged ISA defined bit positions for the Supervisor
Big-Endian (SBE, bit 36) and Machine Big-Endian (MBE, bit 37) fields
in the mstatus register. These are used alongside the existing
MSTATUS_UBE (bit 6) to control data endianness at each privilege level.

The MSTATUS_UBE definition was already present, but SBE and MBE were
missing.
