Let's do it just like the other architectures. Introduce kvm-stub.c
for stubs and kvm_s390x.h for the declarations.
Change license to GPL2+ and keep copyright notice.
As we are dropping the sysemu/kvm.h include from cpu.h, fix up includes.

cpu.h should only contain what really has to be accessed outside of
target/s390x/. Add internal.h which can only be used inside target/s390x/.
Move everything that isn't fast enough to run away and restructure it
right away. We'll move all kvm_* stuff later.
Minor style fixes to avoid checkpatch warning to:
- struct Lowcore: "{" goes into same line as typedef
- struct LowCore: add spaces around "-" in array length calculations
- time2tod() and tod2time(): move "{" to separate line
- get_per_atmid(): add space between ")" and "?". Move cases by one char.
- get_per_atmid(): drop extra paremthesis around (1 << 6)
Change license of new file to GPL2+ and keep copyright notice.

We can tell from the program interrupt code, whether a program interrupt
has to forward the address in the PGM new PSW
(suppressing/terminated/completed) to point at the next instruction, or
if it is nullifying and the PSW address does not have to be incremented.
So let's not modify the PSW address outside of the injection path and
handle this internally. We just have to handle instruction length
auto detection if no valid instruction length can be provided.
This should fix various program interrupt injection paths, where the
PSW was not properly forwarded.

TEST BLOCK was likely once used to execute basic memory
tests, but nowadays it's just a (slow) way to clear a page.

We've currently got 18 architectures in QEMU, and thus 18 target-xxx
folders in the root folder of the QEMU source tree. More architectures
(e.g. RISC-V, AVR) are likely to be included soon, too, so the main
folder of the QEMU sources slowly gets quite overcrowded with the
target-xxx folders.
To disburden the main folder a little bit, let's move the target-xxx
folders into a dedicated target/ folder, so that target-xxx/ simply
becomes target/xxx/ instead.
