Aliaksandr Kalenik 67c727177e LibWeb: Clear all active timers when document is destroyed
This change implements a step from the document's destroy procedure in
the specification, saying that all active timers should be cleared.

By doing this, we also fix the leaking of a document in case where we
have navigated away from a page that has scheduled timers that haven't
yet been triggered.
