feat(node): Add disableAnrDetectionForCallback function

[timfish]

• Ref ANR Detection Improvements Needed for Modal Dialog Handling sentry-electron#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.

I wonder if we should namespace this under anr to control the export count a little, maybe something to think about for v9.

Exporting this seems fine to me.

Mind fixing the merge conflicts? We can merge this in after!

@timfish sorry we were to slow with merging. Would you mind resolving the conflict once more?

Looks good to go!
