IntelFsp2Pkg: Support Config File and Binary delta comparison

BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3567

This patch is to enable config editor to have a new feature that
can spell out the delta between the default configuration files'
data, such as YAML and BSF, against the data stored in the binary.
This can help users understand and track the difference when
modifications are made.
