feat: preloads and nodeIntegration in iframes (#16425) * feat: add support for node / preloads in subframes This feature has delibrately been built / implemented in such a way that it has minimum impact on existing apps / code-paths. Without enabling the new "nodeSupportInSubFrames" option basically none of this new code will be hit. The things that I believe need extra scrutiny are: * Introduction of `event.reply` for IPC events and usage of `event.reply` instead of `event.sender.send()` * Usage of `node::FreeEnvironment(env)` when the new option is enabled in order to avoid memory leaks. I have tested this quite a bit and haven't managed to cause a crash but it is still feature flagged behind the "nodeSupportInSubFrames" flag to avoid potential impact.
