s390x/tcg: introduce and use s390_program_interrupt()
Allows to easily convert more callers of program_interrupt() and to easily introduce new exceptions without forgetting about the cpu state reset. Use s390_program_interrupt() in places where we already had the same pattern. We will later get rid of program_interrupt(). RA != 0 checks are already done behind the scenes.
