build: fix dependency on SDL2

This is a followup on 81d5a24 (build: fix building with MSVC, 2024-03-07) and 68a555e (build: fix __attribute__((aligned(x))) on gcc/clang, 2024-03-09) for the purposes of creating a vcpkg FAudio port. Add a `Requires.private: sdl2` to the pkgconf file for the SDL2 dependency when not using PLATFORM_WIN32. Add the SDL2 dependency to the generated cmake config file when not using PLATFORM_WIN32 as well. Signed-off-by: Rafael Kitover <[email protected]>
