[Patch] BaseTools: Extend the keyword "!include"/"!if" to case-insensitive

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

From: zhijufan <zhijux.fan@intel.com>

Extend the keyword "!include", "!if", etc to case-insensitive.
Current DSC parser already support it, while FDF parser only support
the lower case, so this patch add the support for FDF parser.
