Hook up the WIL fallback error tracer in Terminal (#7864)
This pull request introduces (a very, very stripped-down copy of) the WIL fallback error reporter. It emits error records, usually immediately before the application implodes, into the event stream. This should improve diagnosability of issues that take Terminal down, and allow us to give out a .wprp file to gather traces from users.
