The debug Sdtrig extension defines an optional CSR "mcontext". Since it is optional, this commit adds new CPU configuration "ext_sdtrig_mcontext" and uses property "sdtrig_mcontext" to control whether it is implemented or not. Its predicate and read/write operations are also implemented into CSR ta
