IntelFsp2Pkg: Add Config Editor tool support

BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3396

This is a GUI interface that can be used by users who
would like to change configuration settings directly
from the interface without having to modify the source.

This tool depends on Python GUI tool kit Tkinter.
It runs on both Windows and Linux.

The user needs to load the YAML file along with DLT file
for a specific board into the ConfigEditor, change the desired
configuration values. Finally, generate a new configuration delta
file or a config binary blob for the newly changed values to take
effect. These will be the inputs to the merge tool or the stitch
tool so that new config changes can be merged and stitched into
the final configuration blob.

This tool also supports binary update directly and display FSP
information. It is also backward compatible for BSF file format.

Running Configuration Editor:
python ConfigEditor.py
