[Win] Increase test timeout for slow tests.

[Per Arne Vollan]

There are a number of tests which are finishing just around the timeout limit. We can increase the timeout to make sure these tests will not time out.


06:31:10.330 7616 10 slowest tests that are not marked as SLOW and did not timeout/crash:
06:31:10.330 7616   imported/w3c/web-platform-tests/html/browsers/browsing-the-web/unloading-documents/004.html took 29.3 seconds

What makes these tests so incredibly slow?

I also tested imported/w3c/web-platform-tests/html/browsers/browsing-the-web/unloading-documents/004.html on Mac (debug), and it seems to take almost 30 seconds to finish.

It might be better to mark these tests as slow instead of increasing the test timeout.

I'm still not sure if all these tests are so slow legitimately. Having tests that take 30 seconds is very costly, so we should consider deleting them unless they are exceptionally important.

Also, there might be a few more slow tests, since the script only displays the 10 slowest.

Thanks for reviewing!
