ContentView->ContentViewCore in Shell/ShellManager.

Basically just ensures you can always directly get a ContentViewCore
in ContentShell code. There's too many callers for one CL to switch everyone
over to that.

More clean-up is needed but it seems like the next strings I pull result
in a fair bit of diff. Seems like a small enough chunk that is a logical
change.
