KVM: s390: selftests: add selftest for CMMA migration
Add a selftest for CMMA migration on s390.
The tests cover:
- interaction of dirty tracking and migration mode, see my recent patch
"KVM: s390: disable migration mode when dirty tracking is disabled" [1],
- several invalid calls of KVM_S390_GET_CMMA_BITS, for example: invalid
flags, CMMA support off, with/without peeking
- ensure KVM_S390_GET_CMMA_BITS initally reports all pages as dirty,
- ensure KVM_S390_GET_CMMA_BITS properly skips over holes in memslots, but
also non-dirty pages
Note that without the patch at [1] and the small fix in this series, the
selftests will fail.
