BaseTools: Add DevicePath support for PCD values
Use C code parse device path to output hex string, and Python run command when PCD Value need device path parse. https://bugzilla.tianocore.org/show_bug.cgi?id=541 Contributed-under: TianoCore Contribution Agreement 1.1 Signed-off-by: Yunhua Feng <yunhuax.feng@intel.com> Signed-off-by: Yonghong Zhu <yonghong.zhu@intel.com> Reviewed-by: Liming Gao <liming.gao@intel.com>
