Replace WebPageConfiguration with API::PageConfiguration and expose a C-SPI accessor for it

[Sam Weinig]

This is a step on the way to making WKWebViewConfiguration backed by API::PageConfiguration.

Why the explicit "this->"?

This seems likely to be fragile. What will remind us to keep this in sync as we add data members? Is there a good reason to not use a copy constructor instead? It could be a private one to avoid confusion about reference counting, just as other constructors are private for the same reason.

Is the local variable needed? I think it would read fine without it.

Honestly, I was just blindingly following APIProcessPoolConfiguration, which does it this way. A copy constructor that copy calls would be cleaner. I'll do that for both classes in a follow up.
