sim: bfin: split out common mach/model defines into arch.h [PR sim/20438]

The current machs.h mixes common enums with Blackfin-specific defines.
This causes us troubles with header inclusion order such that we can't
drop the old SIM_CPU typedef (which is duplicated in common code).  By
splitting the two up, we can unwind this dependency chain, and drop the
old typedef.  It also fixes building with older gcc versions.
