### Problem Description
Following #20322 - for me as an Electron user, it's unacceptable that `second-instance` manipulates order of arguments, it's incompatible e.g. with [yargs](https://github.com/yargs/yargs) style (e.g. `myapp.exe -a 1 -b 2`). Current behaviour on Windows is confusing, not well documented.

### Proposed Solution
Although I have [described a workaround](https://github.com/electron/electron/issues/20322#issuecomment-617773983), I would like Electron to somehow overcome Chromium deficiency and pass the original `argv` to the `second-instance` event or pass any custom data comfortably.

I think the best solution could be by adding a string only param msg to `app.requestSingleInstanceLock(msg)` and the [`second-instance`](https://www.electronjs.org/docs/api/app#event-second-instance) would returns the fourth value `msg`.

Other solution may be:
1. `second-instance` would get the original `argv`, not the Chromium one. 
2. If a user pass a custom data `app.requestSingleInstanceLock(argv)`, then the `second-instance` would return this custom data as `argv`, probably processed by `JSON.parse(JSON.stringify(argv))`.
