Followup to emscripten-core#27407 Because `settings.LTO` was an internal setting not used anywhere in JavaScript libraries or runtime code. This change removes `LTO` from `src/settings_internal.js` and stores `-flto` / `-fno-lto` state in `options.lto` on `EmccOptions` instead.

Because
settings.LTOwas an internal setting not used anywhere in JavaScript libraries or runtime code. This change removesLTOfromsrc/settings_internal.jsand stores-flto/-fno-ltostate inoptions.ltoonEmccOptionsinstead.In the long run I hope to use internal settings only for values that need to flow out the the JS compiler.
