WebPageProxy::PolicyDecisionSender should send a struct instead of many parameters

[Kate Cheney]

Right now, PolicyDecisionSender sends 5 parameters. This should be refactored into sending a single struct parameter which contains these values.

These should have default initializers so we don't accidentally use uninitialized memory.
uint64_t navigationID { 0 };
etc.

Can we call this struct just "PolicyDecision"? All classes are data, so "Data" doesn't add meaning here. ("Info" is another words folks are often tempted to use, which I recommend against.)

I also prefer how "send(PolicyDecision {... })" reads like a complete statement: "I am sending a policy decision."

Yes, I'll change both of these before landing. Thanks!
