        Move file-choosing and icon-loading management to FileInputType
        https://bugs.webkit.org/show_bug.cgi?id=62069

        1) Moved the duties of FileChooserClient and FileIconLoaderClient from
        RenderFileUploadControl to FileInputType, along with all of the
        supporting functions.

        2) Moved Icon ownership to FileInputType and exposed accessor on
        HTMInputElement to allow RenderFileUploadControl to query current icon.

        As a result, RenderFileUploadControl is now completely stateless, which is
        neat and clean.

        Refactoring, covered by existing tests.
