[pigeon] Swift errors are unhandled in sync functions #112483
Description
When generating Swift code using Pigeon It seems that there is no way to return an error back to the Flutter/Dart layer. There is a function called wrapError being generated but it never gets used and it's impossible to throw errors from the generated methods because they are not declared as throws in the generated protocol.
