Bug - [MenuToggle] - [No way to show a tooltip with a disabled MenuToggle]

Describe the problem

Following the aria disabled button with tooltip example, I want to apply the same to the MenuToggle but it has no isAriaDisabled or support to show a tooltip when the MenuToggle is disabled

How do you reproduce the problem?

import { MenuToggle, Tooltip } from '@patternfly/react-core';

export const MenuToggleDisabled: React.FunctionComponent = () => <Tooltip content="spooky"><MenuToggle isDisabled>Disabled</MenuToggle></Tooltip>;

Expected behavior

isAriaDisabled is supported and showing a tooltip works.

Is this issue blocking you?

No, for now we just show a disabled DropdownItem when no menu items are available.

从 MenuToggle 组件开始，将其禁用时的行为与 issue 中链接的 ARIA-disabled 按钮示例进行比较。验证由 Tooltip 包裹的 MenuToggle 重现用例，然后添加对 isAriaDisabled 的支持以及测试，展示已禁用的 MenuToggle 可以显示其 tooltip。
