[@types/selectize]: Missing parameters $input and settings

[AndreEckner]

Discussed in #69529

The main Object Selectize.IApi needs the following attributes:
$input - the original JQuery-Object, that was turned into a Selectize-Object
settings - the settings of the current IApi object

From the original JS-code (https://github.com/selectize/selectize.js/blob/master/dist/js/selectize.js):

var Selectize = function($input, settings) {
	var key, i, n, dir, input, self = this;
	input = $input[0];
	input.selectize = self;

	var computedStyle = window.getComputedStyle && window.getComputedStyle(input, null);
	dir = computedStyle ? computedStyle.getPropertyValue('direction') : input.currentStyle && input.currentStyle.direction;
  dir = dir || $input.parents('[dir]:first').attr('dir') || '';

  self.settings = {};

	$.extend(self, {
		order            : 0,
		settings         : settings,                                 // <--
		$input           : $input,                                    // <--
		tabIndex         : $input.attr('tabindex') || '',
		....

Without these two some essential handling of selectize isn't possible.
