[api-minor] Limit the maximum canvas width/height, in addition to its total area (bug 1943094)

Browse source 
Browsers not only limit the maximum total canvas area, but additionally also limit their maximum width/height which affects PDF documents with e.g. very tall and narrow pages.
To address this we add a new `maxCanvasDim` viewer-option, which in Firefox will use a browser preference, such that both the total canvas area and the width/height will affect when CSS-zooming is used.
