Add benchcat: cat + throughput measurements (#15564)
benchcat, "bc" for short, is a tool that I've written over the last two years to help me benchmark OpenConsole and Windows Terminal. Initially it only measured the time it took to print a file as fast as possible, but it's grown to support a number of arguments, including chunk (`WriteFile` call) sizes, repeat counts and VT mode with italic and colorized output. In the future I also wish to add a way to generate the output data on the fly via command line arguments. One unusual trait of benchcat is that it is compiled entirely without CRT and vcruntime. I did this so that I could test it on Windows XP. Also, it's kind of funny seeing how it's only about 11kB. This commit also fixes a couple `$LASTEXITCODE` cases, because our spellchecker was bothering me a lot with this PR and so I just fixed it.
