[ breaking ] remove parsing of dangling binders (#1711)
* [ breaking ] remove parsing of dangling binders

It used to be the case that

```
ID : Type -> Type
ID a = a

test : ID (a : Type) -> a -> a
test = \ a, x => x
```

and

```
head : List $ a -> Maybe a
head [] = Nothing
head (x :: _) = Just x
```

were accepted but these are now rejected because:

* `ID (a : Type) -> a -> a` is parsed as `(ID (a : Type)) -> a -> a`
* `List $ a -> Maybe a` is parsed as `List (a -> Maybe a)`

Similarly if you want to use a lambda / rewrite / let expression as
part of the last argument of an application, the use of `$` or parens
is now mandatory.

This should hopefully allow us to make progress on #1703
