[wasm] Extend liftoff breakpoint test for scope inspection 

This extends the existing test to also print scope information on every
break. Note that the currently printed information is not correct, since
register values are not reconstructed yet. We just always print {-11}
for register values.
Thus the expected output will change with follow-up CL.
