IntelFsp2Pkg/Tools: Enhance PathFv.py to patch Fd file directly

https://bugzilla.tianocore.org/show_bug.cgi?id=4412

After shrinking the FSP (FV) component using FMMT, Image size
in FSP info header is not in sync with the FV length in FV header.
This enhancement helps to patch the FSP image size offset with
correct length & can be used to patch any offset directly on
the FSP Component Fd.
