Add support for :open pseudo-class. This is supported on dialog, details and select elements.

Stylo PR: servo/stylo#297
Testing: WPTs but also data:text/html,<select><option>123</option></select><style>:open { background-color: red; }</style>. There are some tests that now error, these previously failed due to missing :open and now make it further along hitting test_driver.send_keys() which causes them to error
Fixes: #41277.
