Initialize the textLayerFactory once in BaseViewer.setDocument, rather than repeating it for every page

Browse Source 
For reasons that I don't even pretend to understand, the `textLayerFactory` property is determined for *every single* page in the PDF document.
Given that the `TextLayerMode` should be consistent for *all* pages in a document, we obviously could/should define `textLayerFactory` just once instead.
