[api-minor] Add an IsLinearized property to the PDFDocument.documentInfo getter, to allow accessing the linearization status through the API (via PDFDocumentProxy.getMetadata)

Browse source 
There was a (somewhat) recent question on IRC about accessing the linearization status of a PDF document, and this patch contains a simple way to expose that through already existing API methods.
Please note that during setup/parsing in `PDFDocument` the linearization data is already being fetched and parsed, provided of course that it exists. Hence this patch will *not* cause any additional data to be loaded.
