[RFC PATCH v3 44/59] KVM: VMX: Add 'main.c' to wrap VMX and TDX

[isaku.yamahata@intel.com]

From: Sean Christopherson <sean.j.christopherson@intel.com>

Wrap the VMX kvm_x86_ops hooks in preparation of adding TDX, which can
coexist with VMX, i.e. KVM can run both VMs and TDs.  Use 'vt' for the
naming scheme as a nod to VT-x and as a concatenation of VmxTdx.
