[PATCH] BaseTools:Break build if same [LibraryClasses] name is used

[PATCH] BaseTools:Break build if same [LibraryClasses] name is used

[Yonghong Zhu]

From: zhijufan <zhijux.fan@intel.com>

For example if both PackageA and PackageB declare the
[LibraryClasses] name of MyLibClass, that is mapped to
an include file in each package:

PackageA.dec

[LibraryClasses]
  MyLibClass|Include/Library/MyLibClass.h

PackageB.dec

[LibraryClasses]
  MyLibClass|Include/Library/MyLibClass.h
