...with a new Module.catchUnoException JS function that can be used in a JS
catch block to provide the thrown UNO exception as an Any. (For a non-C++
exception, it rethrows the exception, and for a non-UNO C++ exception it maps it
to css.uno.RuntimeException.)
The implementation reuses parts of bridges/source/cpp_uno/gcc3_wasm/, which have
been moved to a new StaticLibrary_emscriptencxxabi.
