PPC/s390: [wasm] Use the modules runtime stub for {DoubleToI}.

Port 98d7b23e

Original Commit Message:

    This uses a WebAssembly runtime stub for the out-of-line {DoubleToI}
    computation instead of a builtin specific to a certain Isolate. It is
    another step towards making {WasmCode} independent of the Isolate.
