refactor(kernel): remove 'let'-expressions
...
We simulate it in the following way:
1- An opaque 'let'-expressions (let x : t := v in b) is encoded as
((fun (x : t), b) v)
We also use a macro (let-macro) to mark this pattern.
Thus, the pretty-printer knows how to display it correctly.
2- Transparent 'let'-expressions are eagerly expanded by the parser.

We reduce the cost by avoiding the allocation of std::functional objects, and the unnecessary increment/decrement of reference counters.

refactor(kernel/converter): implement eta in whnf instead of is_def_eq.
...
Without cumulativity, we do not have problems with Eta at whnf anymore.
When we had cumulativity, we could not not simply reduce
(fun x : A, f x) ==> f
This step is correct only if domain(f) was definitionally equal to f.
Here is a problematic example for systems with cumulativity
Given, f : Type.{2} -> Bool
(fun x : Type.{1}, f x)
