KVM: x86: Move supported EFER bits to kvm_caps

Browse source

Supported EFER bits naturally fits into kvm_caps because it gets
recomputed during vendor initialization (e.g. to account for EFER.SVME
being allowed/disallowed based on nested being enabled/disabled). Move
efer_supported_bits into kvm_caps as supported_efer_bits (for naming
consistency).

As the bitmask is now globally visible as part of kvm_caps, there's
little use for helpers to enable/disable specific bits, so drop them and
open-code updates to kvm_caps.supported_efer_bits.

No functional change intended.
