Pass the full MachineState to the IGVM backend during file processing, instead of just the ConfidentialGuestSupport struct (which is a member of the MachineState). This replaces the cgs parameter of qigvm_process_file() with the machine state to make it available in the IGVM processing context. We will use it later to generate MADT data there to pass to the guest as IGVM parameter.
