Chris Bracken 2091ba8847 Fix parameter type in FlutterDesktopEngineCreate (flutter/engine#25439)
FlutterDesktopEngineCreate is part of our C API. We were using a C++
reference type instead of a C-compatible pointer type.

This is a breaking change to anyone calling this directly; we believe
this should affect few people because the Windows template only uses the
`FlutterEngine` wrapper in
`shell/platform/windows/client_wrapper/include/flutter/flutter_engine.h`.
