feat(node): Add `disableAnrDetectionForCallback` function

[timfish]

• Ref https://github.com/getsentry/sentry-electron/issues/1016

disableAnrDetectionForCallback(() => dialog.openSaveDialog());

Maybe this should just go in the Electron SDK?

I added it for Node because it may be useful outside of Electron and at least here it has access to some private variables and types.
