When creating the CSSParsers for content blocker parsing and compilation, make sure to opt
into hasPseudoClassEnabled so selectors like :has work. The places this was needed were:
- ContentExtensionParser (for parsing the rules)
- ContentExtension (for the global display none rules)
- ContentExtensionStyleSheet (for the other display none rules)

Also update the contentextensions css-display-none test to test this functionality.
