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.

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.

For replace function, when target Ffs and new ffs are with
same size, the output file can not be generated successfully.

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.

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.
