The debug library can be turned on and off so that the debug code does not increase the size of an image.

+
+ Note that a MDEPKG_NDEBUG macro is introduced to switch on/off debug and assert related macros.
+ 1. If MDEPKG_NDEBUG is defined, then debug and assert related macros are NULL.
+ 2. If MDEPKG_NDEBUG is not defined, then PcdDebugProperyMask is used to turn on/off these helper macros.
