[Yonghong Zhu <yonghong.zhu@intel.com>]

From: Yunhua Feng <yunhuax.feng@intel.com>

Case example:
DSC components:
!include Test1.txt

Test1.txt:
 TestPkg/TestDriver.inf {
   <PcdsFixedAtBuild>
    PcdToken.PcdTest1 | "A"
    !include Test2.txt
  }

Test2.txt:
!include Test3.txt

Test3.txt:
PcdToken.PcdTest2 | "B"
