  To: edk2-devel; +Cc: Liming Gao, Yonghong Zhu

when not needed, change from our custom TemplateString class to a simple list of strings.
  this is the .Append->.append changes and "".join(<splat>) changes.
  this parimary affects variables named AutoGenC and AutoGenH
change GenMake dependency searching to not double search.
remove unused sdict class
