src: add SetFastMethodNoSideEffect()

joyeecheung · targos · commit ad5f42d1e9aa · 2023-03-13T11:28:50.000+01:00
The original SetFastMethod() uses v8::SideEffectType::kHasNoSideEffect by default, which is different from SetMethod(). Follow the previous convention and add a new SetFastMethodNoSideEffect() instead.
