Move the injection code for all floating interrupts to interrupt.c
and add a comment.
Also get rid of the #ifdef CONFIG_KVM for the service interrupt.

Despite cautioning that S390CPU is needed for upcoming CPUState
refactorings, commit 5d69c547d9 (s390:
I/O interrupt and machine check injection.) added functions
cpu_inject_io() and cpu_inject_crw_mchk() with CPUS390XState argument,
claiming consistency with cpu_inject_ext().
This complicates making cpu_interrupt() take a CPUState even more and it
required to pass &cpu->env from some S390CPU-aware call sites already,
creating inconsistency elsewhere. Address that.
This also eliminates the need for CPUS390XState in s390_virtio_irq().

This patch creates interrupt.c. The first user is a callback for hw/*
code to trigger an service interrupt for a given sccb value. Several
interrupt types for s390 are floating (can be delivered to all CPUs).
so this code does not belong to a specific CPU.
Other interrupts (like the virtio one) are also floating and can be
moved here later on.
