Add more ConsoleBench tests

[lhecker]

This now covers all major Console APIs.
In the future we could add tests that cover VT sequences as well.

I've scraped every major conhost version since Windows 8.1 from our internal build shares and tested it using this new tool. Here's the resulting measurements.html

You can find a mapping between build numbers and versions here: https://en.wikipedia.org/wiki/List_of_Microsoft_Windows_versions

Before anyone asks, the results for 10586 (Windows 10 version 1511) are not a fluke. 😅 I think that version may have had a faulty circular (text) buffer implementation. I found that there's a perfectly linear relationship between how many rows the text buffer has and how long write operations take.

The good news is that 26000 is faster across pretty much every single metric. The bad news is that some parts still aren't as fast as they used to be. But we'll get there soon enough, I'm sure. 🙂
