This reworks all of mpv's unit tests so they are compiled as separate executables (optional) and run via meson test. Because most of the tests are dependant on mpv's internals, existing compiled objects are leveraged to create static libs and used when necessary. As an aside, a function was moved into video/out/gpu/utils for sanity's sake (otherwise most of vo would have been needed). As a plus, meson multithreads running tests automatically and also the output no longer pollutes the source directory. There are tests that can break due to ffmpeg changes, so they require a specific minimum libavutil version to be built.
