target/i386: Implement mc->kvm_type() to get VM type ...
TDX VM requires VM type KVM_X86_TDX_VM to be passed to
kvm_ioctl(KVM_CREATE_VM). Hence implement mc->kvm_type() for i386
architecture.
If tdx-guest object is specified to confidential-guest-support, like,
qemu -machine ...,confidential-guest-support=tdx0 \
-object tdx-guest,id=tdx0,...
it parses VM type as KVM_X86_TDX_VM. Otherwise, it's KVM_X86_DEFAULT_VM.
Also store the vm_type in MachineState for other code to query what the
VM type is.
