Focus chrome after starting in system tests (#12352)
As discussed in #12293, our systems fail randomly. Usually this is due to another window stealing focus, such as the taskbar or Docker. As system tests are run locally, we shouldn't be killing these processes.
Description of how this pull request fixes the issue:
Use windows API to make the chrome window gain focus
Adds logging that lists the foreground window and open windows if chrome doesn't gain focus
Removes extra sleep time after starting NVDA
