[WebDriver: Dispatch Action] Check if browsing context still open for each tick action (#37393)

As titled. This is what
[spec](https://w3c.github.io/webdriver/#dfn-dispatch-actions-inner)
requires. The motivation is that the previous action might have changed
the browsing context.

Testing: `./mach test-wpt -r --log-raw "D:\servo test log\all.txt"
.\tests\wpt\tests\webdriver\tests\classic\ --product servodriver`
