Add arithmetic-specific, runtime, proof-macros. (#4992)

We'll use this to gate farkas-coefficient machinery after we remove the
old proof-macros.

I've changed the macros slightly from the proof-new branch: I removed the dependence on options::proof() (no longer wanted) and options::unsatCores() (I had copied this from the original proof macros, but it's not needed either, since we're in a theory).
