frame properties now have the const-ness semantics of member variables

In https://bugzilla.mozilla.org/show_bug.cgi?id=1353187 I just
landed a patch that gives frame properties (which act like extended
member variables) the semantics of member variables, so that if you
have a |const nsIFrame*| you can still Get a property, but you can't
Set or Remove it.

This required a pretty small number of adjustments to existing code.

(I did this so that the primary patch in that bug wouldn't need to
const_cast in order to set a frame state bit when a frame has
properties, but it seemed like a good thing to do anyway.)

             And to whom I was like to give offense.
