d8a171b895 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.

7977926811 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.

e93ee87643 BaseTools: FMMT: Fix incorrect size calculation in ModifyTest()
There is another issue in FvHander.py similar to the one fixed by
a60334ad59 ("BaseTools: Fix FMMT FvHandler Padding operation issue").

For a guided section (ParTree.Data.Type == 0x02), the length of
ParTree.Data.OriData is used to obtain the original size of the data even
after ParTree.Data.OriData has changed, which is incorrect.

This caused the following issue I observed. I built OVMF image for Aarch64
and then tried to add a couple FFS modules to it with 'FMMT -a [...]'. The
resulting image turned out to be invalid: the total size of the image was
less than the size of the firmware volume within it.

UEFITool failed to load such firmware image and complained:
"parseRawArea: one of objects inside overlaps the end of data".

This patch fixes the issue.

a60334ad59 BaseTools: Fix FMMT FvHandler Padding operation issue
When using the FMMT FvHandler function, new padding size
should be calculated correctly comparing with origin ffs
and new ffs, else it will cause the binary size changes.
This patch is used to fix the bug.

7c6ef8eac2 BaseTools: Fix FMMT Compress wrong behavior
When using the replace function, if the replaced file
located in a compress section, then the tool will re-build
the section. As the compress status set in the wrong place,
in some situation, the compress will do twice times which is
a wrong behavior.

This patch is used to fix this issue.

b5f5106c1e BaseTools: FMMT replace new free space fixing in replace
In FMMT replace function, when newffs size <= targetffs size,
the new free space is calculated wrong as loss the pad data delta size.
That will cause invalid binary generated.
This patch fixes this issue.

a64b944942 BaseTools: Add FMMT Python Tool
The FMMT python tool is used for firmware files operation, which has
the Fv/FFs-based 'View'&'Add'&'Delete'&'Replace' operation function:

1.Parse a FD(Firmware Device) / FV(Firmware Volume) / FFS(Firmware Files)
2.Add a new FFS into a FV file (both included in a FD file or not)
3.Replace an FFS in a FV file with a new FFS file
4.Delete an FFS in a FV file (both included in a FD file or not)
5.Extract the FFS from a FV file (both included in a FD file or not)

This version of FMMT Python tool does not support PEIM rebase feature,
this feature will be added in future update.

Currently the FMMT C tool is saved in edk2-staging repo, but its
quality and coding style can't meet the Edk2 quality, which is hard to
maintain (Hard/Duplicate Code; Regression bugs; Restrict usage).

The new Python version keeps same functions with origin C version. It
has higher quality and better coding style, and it is much easier to
extend new functions and to maintain.
