Maintain a TDX specific supported CPUID set, and use it to mask the common supported CPUID value of KVM. It can avoid newly added supported features (reported via KVM_GET_SUPPORTED_CPUID) for common VMs being falsely reported as supported for TDX. As the first step, initialize the TDX supported CPUID set with all the configurable CPUID bits. It's not complete because there are other CPUID bits are supported for TDX but not reported as directly configurable. E.g. the XFAM related bits, attribute related bits and fixed-1 bits. They will be handled in the future. Also, what matters are the CPUID bits related to QEMU's feature word. Only mask the CPUID leafs which are feature word leaf.
