Support SomeStruct::new() function call syntax

[sbillig]

What is wrong?

Type-associated functions can currently be called by using a . but not a ::. For example:

struct Rectangle:
  h: u256
  w: u256
  pub fn square(x: u256) -> Rectangle:
    return Rectangle(h=x, w=x)
  pub fn area(self) -> u256:
    return self.h * self.w

fn do_square_things():
  let s: Rectangle = Rectangle::square(10)
  assert s.area() == 100

The Rectangle::square(10) call above panics with something like

thread 'struct_fn' panicked at 'not yet implemented: cannot access items in types yet', crates/analyzer/src/namespace/items.rs:106:30

changing it to Rectangle.square(10) works. This syntax should be disabled, and :: should be fixed.

How can it be fixed
