i386/tdx: Track mem_ptr for each firmware entry of TDVF
For each TDVF sections, QEMU needs to copy the content to guest private memory via KVM API (KVM_TDX_INIT_MEM_REGION). Introduce a field @mem_ptr for TdxFirmwareEntry to track the memory pointer of each TDVF sections. So that QEMU can add/copy them to guest private memory later. TDVF sections can be classified into two groups: - Firmware itself, e.g., TDVF BFV and CFV, that located separately from guest RAM. Its memory pointer is the bios pointer. - Sections located at guest RAM, e.g., TEMP_MEM and TD_HOB. mmap a new memory range for them. Register a machine_init_done callback to do the stuff.
