Break dependencies between PresentationMode and other code, and add PresentationMode related utility methods to PDFViewer

Browse source 
This patch:
 - Adds a couple of utility methods to `PDFViewer` to enable checking `presentationModeState` without cumbersome comparisons.

 - Disentangles `PresentationMode` from `PDFHistory` and `HandTool`, by adding event listeners for `presentationmodechanged` to both of them.

 - Adds a utility function to `PDFViewerApplication` for requesting PresentationMode.

 - Prevents initialization of `PresentationMode` if the browser does not support the fullscreen API.
