[api-minor] Change the getViewport method, on PDFPageProxy, to take a parameter object rather than a bunch of (randomly) ordered parameters

Browse source 
If, as PR 10368 suggests, more parameters should be added to `getViewport` I think that it would be a mistake to not change the signature *first* to avoid needlessly unwieldy call-sites.

To not break any existing code and third-party use-cases, this is obviously implemented with a deprecation warning *and* with a working fallback[1] for the old method signature.

[1] This is limited to `GENERIC` builds, which should be sufficient.
