[GeckoView] Ignore Scroll/Spread-modes in the PDFViewer setters

Browse Source 
Rather than sprinkling pre-processor statements throughout the viewer-code, simply "disable" the relevant `PDFViewer` setters instead.

Also, given that the GeckoView-specific viewer doesn't have a sidebar we don't actually need to explicitly ignore a `pageMode` during loading.
