Subject: [PATCH] avfilter/vf_libplacebo: replace preproc directive in
 function-like macros

MSVC build was failing due to preprocessor directives being used within function-like macro argument lists, which is undefined behavior according to the C11 spec. Fixed by replacing the directive blocks with macro definitions outside of the macro invocations.
