MdeModulePkg: Add new macros and refine codes

Browse Source 
Add 2 macros inNetLib.h
#define  IP4_MASK_MAX          32
#define  IP6_PREFIX_MAX        128
we will use these two macros to check the max mask/prefix length,
instead of
#define  IP4_MASK_NUM          33
#define  IP6_PREFIX_NUM        129
which means a valid number.
This will make the code readability and maintainability.
