[Debugger] Allow debugging page-rendering from the /Ref, in addition to the pageNumber

Browse Source 
Currently it's only possible to trigger page-render debugging through the page number, but when looking at the /Pages tree it's often not immediately obvious what the page number actually is.
However, the /Ref of the page is directly available and it's thus handy to be able to use that one instead to enable page-render debugging.
