Luke Warlow bd779d141a script: Add support for :open pseudo-class (#42195) ...

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.
