KVM: selftests: Add a CPUID testcase for KVM_SET_CPUID2 with runtime updates
Add a CPUID testcase to verify that KVM allows KVM_SET_CPUID2 after (or in
conjunction with) runtime updates. This is a regression test for the bug
introduced by commit 93da6af3ae56 ("KVM: x86: Defer runtime updates of
dynamic CPUID bits until CPUID emulation"), where KVM would incorrectly
reject KVM_SET_CPUID due to a not handling a pending runtime update on the
current CPUID, resulting in a false mismatch between the "old" and "new"
CPUID entries.
