KVM selftests changes for 7.1

 - Add support for Hygon CPUs in KVM selftests.

 - Fix a bug in the MSR test where it would get false failures on AMD/Hygon
   CPUs with exactly one of RDPID or RDTSCP.

 - Add an MADV_COLLAPSE testcase for guest_memfd as a regression test for a
   bug where the kernel would attempt to collapse guest_memfd folios against
   KVM's will.
