Subject: [PATCH 1/1] BaseTools: INF should use latest Pcd value instead of default value

This patch is a bug fix about FeatureFlagExpression in INF file:
 INF [Source] section now unconditionally use Pcd default value in DEC  when handling FeatureFlagExpression, it is wrong.
 If a Pcd value has been set in the DSC file, we should use latest  value in DSC instead of default value.
