  [sanitizer] Apply AlwaysIn/Out in parseSanitizeArgs (#129405)

For backwards compatibility, `parseSanitizeArgs`/`parseSanitizeTrapArgs` had an incomplete refactoring in
https://github.com/llvm/llvm-project/pull/119819, in order to accommodate the special case of vptr in -fsanitize=undefined and its interaction with -fsanitize-trap=undefined. Now that vptr is no longer part of -fsanitize=undefined (https://github.com/llvm/llvm-project/pull/121115), this patch changes parseSanitizeArgs to apply the AlwaysIn/Out invariants in parseSanitizeArgs, which allows simplifying calls to parseSanitizeArgs.

This is not quite NFC: it changes the error message of -fsanitize-trap=vptr.
