KVM x86/pmu changes for 6.11

Browse source

- Don't advertise IA32_PERF_GLOBAL_OVF_CTRL as an MSR-to-be-saved, as it reads
    '0' and writes from userspace are ignored.
 
  - Update to the newfangled Intel CPU FMS infrastructure.
 
  - Use macros instead of open-coded literals to clean up KVM's manipulation of
    FIXED_CTR_CTRL MSRs.
