Fix a bug about parse the macro value which use another macro.
Use the following example to verify:
[Define]
DEFINE M1 = V1
DEFINE M2 = $(M1)/V2
!include $(M2)/pcd.dsc
The old code will failed parse M2 and cause following error:
Traceback (most recent call last):
File "Edk2\IntelFsp2Pkg\Tools\GenCfgOpt.py", line 1550, in <module>
sys.exit(Main())
File "Edk2\IntelFsp2Pkg\Tools\GenCfgOpt.py", line 1513, in Main
if GenCfgOpt.ParseDscFile(DscFile, FvDir) != 0:
File "Edk2\IntelFsp2Pkg\Tools\GenCfgOpt.py", line 533, in ParseDscFile
NewDscLines = IncludeDsc.readlines()
ValueError: I/O operation on closed file.
The tool should support the value use another macro, and expand it.
