[PATCH] BaseTools: Support DSC component !include PCD items

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

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

DSC format:
[Components]
  TestPkg/TestDriver.inf {
    <PcdsFixedAtBuild>
      !include TestPkg/Test.txt
  }

Test.txt content:
PcdToken.PcdCName | 0x123

Per spec we should support this usage.
