Cinnamon Accessibility: Add Keyboard Shortcut to toggle zoom

[joepitt91]

Please add a keyboard shortcut under the Universal Access section to toggle zoom on and off, I'd suggest alt+super+0 as the default as then all three zoom controls are next to each other and easy to remember.

There are two main reasons this is needed:

1. Visually impaired new users: When I first installed Cinnamon as a visually impaired user it was very hard to see enough to navigate into System Settings, into Accessibility and locate and toggle enable zoom - being able to just press a keyboard combo would have made this much easier.
2. Temporarily zooming out (e.g. to watch a video full screen): while you can use Super+Mouse Wheel to zoom in and out, this is very clunky to use regularly and can be very tricky to get back to the right zoom level, a simple toggle zoom keyboard shortcut would make this instantaneous.

Other than this and linuxmint/cinnamon#12868, I'm really happy with the builtin magnifier so far (I've only been using Cinnamon for a couple of days at this point).

This is related to, but I think different from:

For anyone finding this looking for a workaround, create this script and bind a custom keyboard shortcut to it:
