KVM: selftests: Test all immutable non-format bits in PERF_CAPABILITIES
Add negative testing of all immutable bits in PERF_CAPABILITIES, i.e. single bits that are reserved-0 or are effectively reserved-1 by KVM. Omit LBR and PEBS format bits from the test as it's easier to test them manually than it is to add safeguards to the comment path, e.g. toggling a single bit can yield a format of '0', which is legal as a "disable" value.
