Reduce some duplication when toggling buttons in the viewer toolbars

Browse source 
Currently we repeat the same code in lots of places, to update the "toggled" class and "aria-checked" attribute, when various toolbar buttons are clicked.

For the MOZCENTRAL build-target this patch reduces the size of the *built* `web/viewer.js` file by just over `1.2` kilo-bytes.
