[DSP-109] Add permanent entrypoints to upgradeable contract

Description

Here I add permanent entrypoints to upgradeable contract which are useful for implementing interfaces like FA1.2. This is a breaking change.

This required adding another Lorentz entrypoints derivation way - in order to stay modular.

After this MR I hope to make some other pending changing in that contract which we could not apply without breaking compatibility. Hopefully, it's fine that I update the contract in place, not create a new one; AFAIU two our projects which use it can be updated, and probably no one else uses upgradeable contract in production ATM.
