[wasm] WasmRunner can run tests with I64 parameters and return value.

I extended the Int64Lowering to lower calls, loads, stores, returns, and
parameters and apply the lowering on both the test function TF graph and
the WasmRunner TF graph.

The lowering of calls also requires an adjustment of the call descriptor.
