Avoid stderr pollution from chrome/electron logging

[ssbarnea]

At this moment, while running tests, almost on any platforms, there are a series of notifications or warnings coming from chrome that cannot be addressed. These cannot really be addressed and they make reading the console considerably harder, especially as they are generated by a different process and they appear at random locations in output.

I investigated a redirection of stderr and it seems to be considerably improve the experience. Example of thing that no longer populated the console:

2022-03-03 09:10:37.800 Electron[55575:17722594] ApplePersistence=NO

2022-03-03 09:10:38.695 Code Helper (Renderer)[55583:17722698] CoreText note: Client requested name ".NewYork-Regular", it will get Times-Roman rather than the intended font. All system UI font access should be through proper APIs such as CTFontCreateUIFontForLanguage() or +[NSFont systemFontOfSize:].

I am not saying that we should sent this to /dev/null, just that we should dump it to an stderr.log instead, so it can be analyzed if really needed.

This can be done by consumers fairly easily be appending 2> stderr.log to their command if they find the output unpleasant. Doing that automatically would make debugging any failures significantly harder (e.g. lack of a framebuffer in CI, which is a pretty common stumbling block), so I'm disinclined to do this.
