Downstream feature request: flutter/flutter#60189

#35851 now supports translating obfuscated Dart stacks into the original stack, but as far as I understand, after applying --split-debug-info, we no longer have enough symbols left in the binary to then generate Xcode Debugging Symbols (dSym) from the binary/framework. This means users can no longer symbolize native call stacks into Dart call stacks.

Would it be possible for --split-debug-info to output both a obfuscated Dart -> Dart map as well as a native -> Dart map?
