Shannon Booth e124ef52ee LibJS+LibWeb: Set [[CanBlock]] false to Agent for window agent
similar-origin window agents have the [[CanBlock]] flag set to false.
Achieve this by hooking up JS's concept with an agent to HTML::Agent.
For now, this is only hooked up to the similar-origin window agent
case but should be extended to the other agent types in the future.
