1. [WGSL] Variables initializer shouldn't be a reference …

   When initializing a variable, the value used to initialize it should be unpacked
   if it's a reference. E.g.:
   
   var a = 0;
   var b = a;
   b = 1;
   
   The above program should not change the value of `a`, and references to `b` should
   have type `ref<i32>`, not `ref<ref<i32>>`. In order to fix that, when we infer the
   type of a variable initializer (which doesn't have an explicit type annotation), if
   the is a reference (as it would be for `a` in the example above, which would have type
   `ref<i32>`), we should use the referenced type instead (i.e. `i32` in this example)
