* Fix inconsistency in FREEZE_PROOF flag (#74102)
Although all objects that _have_ the flag attach it to
`resistance_flags` (which is what the define location implies it's
supposed to be set on), all the code that checked it for the purposes of
applying the freezing element used `obj_flags`.
As far as I can tell, that meant the only things immune to freezing were
things that "blocked z falling from above".
Also, freezing only happens with some obscure weapons and low
temperature water vapour, but hey 🤷.
🆑 coiax
fix: Coffee cups are now correctly immune to becoming frozen by low
temperature water vapour.

Shout out to RaveRadbury who helped me with debugging this.
