REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1548 For clang compiler, This change will make the generated image not include the absolute file path. If so, the generated debug image can be reproduced in the different root directory. Also, it will reduce the size of debug image size. To do so, use __FILE_NAME__ macro to replace __FILE__. __FILE_NAME__ is Clang-specific extension that functions similar to __FILE__ but only renders the last path component (the filename) instead of an invocation dependent full path to that file, and __FILE_NAME__ is introduced since clang 9.
