st/settings: Add magnifier activation property and bind to settings

Browse Source 
The same code for reading the current magnifier state is repeated in both
shell-recorder, shell-screenshot and magnifier itself.
So to move this inside a property of st-settings so that we can refer to it
all over the places removing duplications.
