I entered a new BZ https://bugzilla.tianocore.org/show_bug.cgi?id=1804 to track the [Sources] section check function.
Agree that "minimize the performance hit by saving the data from ModuleMakefile.GetFileDependency() to memory and reuse it later in GenMake to save on IO and search."

It might be better to make it a script. But this is only going to happen when the hash feature is enabled, not ever build. Also we can minimize the performance hit by saving the data from ModuleMakefile.GetFileDependency() to memory and reuse it later in GenMake to save on IO and search.
