KVM: x86: Do VMX/SVM support checks directly in vendor code

Browse source

Do basic VMX/SVM support checks directly in vendor code instead of
implementing them via kvm_x86_ops hooks.  Beyond the superficial benefit
of providing common messages, which isn't even clearly a net positive
since vendor code can provide more precise/detailed messages, there's
zero advantage to bouncing through common x86 code.

Consolidating the checks will also simplify performing the checks
across all CPUs (in a future patch).
