Add ThinLTO support via -lto:thin and -lto:thin-files flags
- Add -lto:thin and -lto:thin-files CLI flags with validation
- Emit LLVM bitcode (.bc) instead of object files when LTO is enabled
- Pass -flto=thin and -flto-jobs to clang/lld linkers
- Guard linkage corrections to skip declarations without definitions
(required for LTO where declarations appear across modules)
- Allow module-per-file with LTO even at higher optimization levels
