[declare] Merge `DeclareObl` into `Declare`

This is needed as a first step to refactor and unify the obligation
save path and state; in particular `Equations` is a heavy user of
Hooks to modify obligations state, thus in order to make the hook
aware of this we need to place the obligation state before the hook.

As a good side-effect, `inline_private_constants` and `Hook.call` are
not exported from `Declare` anymore.
