Port b2abe2cf

Original Commit Message:

    This makes the WasmCompileLazy builtin push a new WASM_COMPILE_LAZY
    frame type. We can thereby remove the workaround to return a relocated
    instance from the underlying runtime function. It also removes the last
    remaining embedded code objects from {WasmCode} objects.
