STYLE: Remove p->Initialize() calls directly after p = T::New()

For any ITK type `T`, `T::New()` does already initialize the object it returns.

Using Notepad++, Replace in Files, doing:

    Find what:  (\w+)([ ]+= .+::New\(\);\r\n)[\r\n]* [ ]+\1->Initialize\(\);
    Replace with:  $1$2
    Filters: itk*.* !+\test
    Directory: D:\src\ITK\Modules
    [v] Match case
    (*) Regular expression

Manually removed an obsolete comment saying `Clear elements`.
