1.Add FFS file type check: Only allow rebase operation for EFI_FV_FILETYPE_SECURITY_CORE, EFI_FV_FILETYPE_PEI_CORE, EFI_FV_FILETYPE_DXE_CORE, EFI_FV_FILETYPE_PEIM, EFI_FV_FILETYPE_DRIVER, EFI_FV_FILETYPE_COMBINED_PEIM_DRIVER,EFI_FV_FILETYPE_FIRMWARE_VOLUME_IMAGE types, improving safety and compliance. 2.Automatically detect and complete the PE/COFF or TE image relocation table (reloc section) to ensure integrity and compatibility of the rebase operation. 3.After rebase, automatically update FFS checksum and FV header information to ensure correct data structure. 4.Support recursive processing for nested FVs, ensuring all related FFS files' PE/TE images are properly rebased and reloc tables are completed. 5.Use table-driven architecture for relocation types, making it easier to extend to more platforms. 6.Improve error handling and logging for better robustness and maintainability. Please attention, only IA32 and X64 PE/COFF image are supported now. For other Arch, will support it after testing. Signed-off-by: Yuwei Chen <yuwei.chen@intel.com>
