Update StyleSheet.insertRule WebIDL to make index optional.
Update wpt metadata to show the new passes.
Add one test as crashing since currently passing an \@import rule to insertRule

Add optional annotations for initEvent method of Event interface
Added `optional` and default values to parameters `bubbles` and `cancelable` of `initEvent` of `Event`.
I tried to update test results, but there seem to be no differences at all.
I checked similar code where `optional` is used, and there seems to be no special handling in Rust. If that is not the case with this issue, please let me know and I'll commit more follow-ups.
