[wdspec] change test_..._closes_browsing_context

[sadym-chromium]

The tests relied on the script closing browsing context which causes "Scripts may only close windows that were opened by a script".

Open context with window.open to allow it to be closed by script.

This test is specific to handling of actions and when a event handler closes the tab/window. We should not make use of a different BiDi command here, but as you say need to open a new window first by using window.open().

Not sure why we set this preference in Firefox by default to change the default behavior which is a bit concerning and I wonder how other wpt tests actually result in when we would change that. @jgraham do you have an idea?

We need to rely on other BiDi commands. Changed approach to open a window via script, which uses script.evaluate command to open the window and browsingContext.load to verify the window is opened.

the concerns are addressed

Thanks for the fix @sadym-chromium! Please note that we have similar tests for WebDriver classic as well. Would you be able to provide a similar PR?

Waiting for the new window to be loaded in classic is way more tricky. Do you have an idea on how to make it?
