Update mingw and macOS SDL libraries to 2.24.0. (MSVC .lib files and Xcode project haven't been updated.) There is now a separate SDL dylib for macOS Universal Binary 1 and 2 because SDL 2.24.0 dropped support for macOS 10.6 (which is last to support x86). Documentation says SDL 2.24.0 also dropped macOS 10.7 and 10.8 too. So UB2 is now 10.9 or later while 10.5 to 10.8 live in UB1. Compiled using osxcross with macOS 11.3 SDK. Ran "strip -x" on Windows and macOS libraries. Ad-hoc signed dylib using PyOxidizer rcodesign to fix digest checksums after strip.
