refactor(library,hott): remove coercions between algebraic structures
...
They are classes, and mixing coercion with type class resolution is a
recipe for disaster (aka counterintuitive behavior).

feat(hott): port parts of natural numbers and integers from standard library to HoTT
...
This also involves:
- adding definitions about logic and natural numbers existing in the standard library to init
- porting the current algebraic hierarchy

refactor(frontends/lean): add 'attribute' command
...
The new command provides a uniform way to set declaration attributes.
It replaces the commands: class, instance, coercion, multiple_instances,
reducible, irreducible
