	 * This function takes an array of arguments and generates a style declaration string
	 * based on the provided arguments. The generated style declaration can be used
	 * to apply CSS styles to elements.
	 *
	 * This function is equivalent of JS function:
	 * {@link /docs/builder-api/js/style-library/overflow-icon-style-declaration/ overlayIconStyleDeclaration}
	 * located in `@divi/style-library` package.

	 * @since ??

	 * @param array $args {
	 *     An array of arguments.
	 *
	 *     @type string      $attrValue   The attribute value.
	 *     @type array|bool  $important   Optional. Whether to add `!important` to the CSS. Default `false`.
	 *     @type string      $returnType  Optional. The return type of the style declaration. Default `string`.
	 *                                    One of `string`, or `key_value_pair`
	 *                                      - If `string`, the style declaration will be returned as a string.
	 *                                      - If `key_value_pair`, the style declaration will be returned as an array of key-value pairs.
	 * }
	 *
	 * @return array|string The generated style declaration.

	 * ```php
	 *   $args = [
	 *       'attrValue'   => 'value',
	 *       'important'   => true,
	 *       'returnType'  => 'array',
