The issue is that libavfilter depends on libavcodec, and when doing a static build, if libavcodec also includes "libavfilter/vulkan.c", then during link-time, compiling programs will fail as there would be multiple definitions of the same symbols in both libavfilter and libavcodec's object files. Linkers are, however, more permitting if both files that include a common file that's used as a template are one-to-one identical. Hence, to make both files the same in the future, export all avfilter specific functions to a separate file. There is some work in progress to make templated files like this be compiled only once, so this is not a long-term solution. This also removes a macro that could be used to toggle SPIRV compilation capability on #include-time, as this could cause the files to be different.
