BaseTools: Update ValueExpressionEx for flexible PCD
1. Byte array number should less than 0xFF. 2. Add SplitPcdValueString for PCD split Cc: Liming Gao <liming.gao@intel.com> Cc: Yonghong Zhu <yonghong.zhu@intel.com> Contributed-under: TianoCore Contribution Agreement 1.1 Signed-off-by: Yunhua Feng <yunhuax.feng@intel.com> Reviewed-by: Yonghong Zhu <yonghong.zhu@intel.com>
