[PATCH] [TargetInfo] Move LinkerInputFile to TargetInfo and rename more specific name

[Shankar Kalpathi Easwaran]

  TargetInfo should not be used to create Flavor specific atoms. I am ok with ELFTargetInfo have another LinkerInternal File, but I think the current design on changing TargetInfo is not clean either. We might need to come up with something that needs to share functionality across multiple flavors, which doesnot exist currently.
