This patch removes many annotations that are not relevant anymore since we don't support or test back-deploying to macOS < 10.13. It also cleans up raw usage of target triples to identify versions of dylibs shipped on prior versions of macOS, and uses the target-agnostic Lit features instead. Finally, it reorders both the Lit backdeployment features and the corresponding availability macros in the library in a way that makes more sense, and reformulates the Lit backdeployment features in terms of when a version of LLVM was introduced instead of encoding the system versions on which it hasn't been introduced yet. Although one can be derived from the other, encoding the negative form is extremely error-prone. Fixes #80901
