semihosting: create SemihostingConfig structure and semihost.h
Remove semihosting_enabled and semihosting_target and replace them with SemihostingConfig structure containing equivalent fields. The structure is defined in vl.c where it is actually set. Also introduce separate header file include/exec/semihost.h allowing to access semihosting config related stuff from target specific semihosting code.
