[wasm] Remove interpreter compilation hint 

The interpreter will be un-shipped soon, hence we cannot have a
compilation hint for interpreted execution.
This CL removes the respective enum value, removes a test which
specifically tested this one option, and adapts other code to use one of
the remaining hints.
