This Pull Request fixes/closes #1601
It changes the following:
- implements `FormalParameter` using `syntax::ast::node::declaration::Declaration` as
```
pub struct FormalParameter {
declaration: Declaration,
is_rest_param: bool,
}
```
- changes `fn test_formatting(source: &'static str)` in `ast::node` to setup tests based on the new struct definition
- changes in various tests using `FormalParameter`
- changes in files using `FormalParameter`
What it does not change:
- if the function uses `FormalParameter` but does not seem affected due to the changed definition it is not altered while keeping all the required features i.e. if it wasn't affected but ended up giving undesired (not error) behaviour it has been changed
