x86/vmware: Update platform detection code for VMCALL/VMMCALL hypercalls

Vmware has historically used an INL instruction for this, but recent
hardware versions support using VMCALL/VMMCALL instead, so use this
method if supported at platform detection time. Explicitly code separate
macro versions since the alternatives self-patching has not been
performed at platform detection time.

Also put tighter constraints on the assembly input parameters.
