[IR] Split const folding into necessary one and for optimizations only

In this commit we have a lot of change in test data. This was caused
by the way where we evaluate constants. We split constant evaluation
into two distinct parts: only necessary evaluations for `fir2ir`
(like const val and annotations) and optimizations for lowering.
Now we don't do all constant evaluation on `fir2ir`, but IR
dump is executed after this phase, so test data changed.
