Update ic_mock.wat

candid-extractor requires a mock WASM (ic_mock.wat) which provides ic0 imports.

Such ic_mock.wat is directly generated from the system API.

When interface-spec releases a new version that modify ic0 system API:

1. replace ic0.txt in the root of this project;
2. execute cargo run --example=generate_mock_wat;

ic_mock.wat should be updated.
