Make CPDF_Page retainable.
Small step to reducing the differences between XFA and non-XFA. We
still use the RetainPtr pretty much as if it were an unique_ptr, in
that we're not yet caching pages and handing out multiple pointers
to the same page in the non-XFA case.
The one change is in page view cleanup, where we no longer need a
boolean and can take (sufficient) page ownership with a RetainPtr.
Tidy up some document.h -> page.h -> document.h circular inclusion
while we're at it.
NOTE: Wait for imminent branch to pass before landing. We'll want
this to bake a while.
