KVM: x86/pmu: Disable RDPMC interception for compatible mediated vPMU

Disable RDPMC interception for vCPUs with a mediated vPMU that is
compatible with the host PMU, i.e. that doesn't require KVM emulation of
RDPMC to honor the guest's vCPU model.  With a mediated vPMU, all guest
state accessible via RDPMC is loaded into hardware while the guest is
running.

Adust RDPMC interception only for non-TDX guests, as the TDX module is
responsible for managing RDPMC intercepts based on the TD configuration.
