properties_view: Move expressions to UI files

Browse source 
Currently Loupe leaks expressions created in-code. This
is because expressions need to be unwatched in order to be
dropped. Since we'd need to hold a reference to the watch
ourselves and unwatch them in dispose, our code would
become more cumbersome if we were to try to handle this properly.

This commit moves the expressions on LpPropertiesView to the
UI file, as GTK handles cleaning up the expressions it creates,
without any extra consideration on the app side.
