move `_≗_` from `Relation.Binary.PropositionalEquality` to `*.Core`

It has a very straightforward definition (if you unwind the current overly complex one) and is used a fair amount, which then drags in quite a bit more than is needed. In particular, Data.Product.Properties is otherwise very simple, but lies higher up in the dependency graph due to this single definition.
This is fine to do!
And yes that definition is definitely a little overly complex!
I agree with each of you!
