Upon migration, we expect storage keys being set by the guest to be preserved, so add a test for it. We keep 128 pages and set predictable storage keys. Then, we migrate and check they can be read back and the respective access restrictions are in place when the access key in the PSW doesn't match. TCG currently doesn't implement key-controlled protection, hence add the relevant tests as xfails. To this end, a check_pgm_int_xfail() is useful, which is also added in this series.
