New fixity/iterator syntax (#2332)
- Closes #2330
- Closes #2329 

This pr implements the syntax changes described in #2330. It drops
support for the old yaml-based syntax.
Some valid examples:
```
syntax iterator for {init := 1; range := 1};

syntax fixity cons := binary {assoc := right};
syntax fixity cmp := binary;
syntax fixity cmp := binary {}; -- debatable whether we want to accept empty {} or not. I think we should
```
# Future work
This pr creates an asymmetry between iterators and operators
definitions. Iterators definition do not require a constructor. We could
add it to make it homogeneous, but it looks a bit redundant:
```
syntax iterator for := mkIterator {init := 1; range := 1};
```

We could consider merging iterator and fixity declarations with this
alternative syntax.
```
syntax XXX for := iterator {init := 1; range := 1};

syntax XXX cons := binary {assoc := right};
```
where `XXX` is a common keyword. Suggestion by @lukaszcz XXX = declare
