PR Summary

Changes are as follows:

• Fix FixupFileName to not load an assembly in module analysis if the assembly path has been resolved. This way, the module analysis via Get-Module -ListAvailable wouldn't load the module assemblies unexpectedly.
• Update the RequiredAssemblies processing to not add the same assembly to the ToProcess list twice, so that we can avoid loading the same assembly twice.
• Remove unneeded #if !CoreCLR section about CLR version and .NET framework version.
