Add support for the /Catalog Base-URI when resolving URLs (issue 14802)

Browse source 
As far as I can tell, this is actually the very first time that we've seen a PDF document with a Base-URI specified in the /Catalog; please refer to the specification:
https://web.archive.org/web/20220309040754if_/https://www.adobe.com/content/dam/acom/en/devnet/pdf/pdfs/PDF32000_2008.pdf#G11.2097122

To simplify the overall implementation, this new parameter is accessed via the existing `BasePdfManager.docBaseUrl`-getter and will thus override any user-specified `docBaseUrl` API-parameter.
