BaseTools: Enable FMMT Rebase function
This patch adds and improves the rebase functionality
for firmware images (PE/COFF/TE) in the FMMT tool.
Key features include:
1.Automatically rebases PE/COFF/TE images within FFS files
when the firmware volume (FV) layout is adjusted or FFS files
are moved, ensuring correct loading and execution at new addresses.
2.Implements recursive rebase logic for nested sections,
guaranteeing all relevant images are properly relocated.
3.Adds support for rebasing subsequent FFS files within the same FV,
enhancing compatibility and stability during firmware layout changes.
4.Core code changes are mainly in FvHandler.py, BiosTreeNode.py,
and BinaryFactoryProduct.py, covering rebase flag detection, address
calculation,
and actual relocation operations.
5.This feature improves the flexibility of firmware space management
and enhances the automation and reliability of the FMMT tool.

BaseTools: Enhance FMMT rebase feature with FFS type check
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.
