PR description

• 修复 [Nav] in collapse mode hover item will lost open state which exist before collapse #2558 存在的问题
• 修改说明：

1. Sub 移除 updateOpen的 adapter，直接换成 updateOpenKeys
   原有的 SubNav 中，将 openKeys的更新耦合在了两个操作中: updateOpen时，判断 dropdown的 visible决定是 addOpenKeys，还是 removeOpenKeys。
   foundation 中 调用 updateOpen时，无法直接决定 newOpenKeys。但是实际上在两处仅有的 updateOpen调用中，它的前一步骤已经把最新的 newOpenKeys算出来了，没有必要再在 updateOpen adapter中重新计算。此处应该信赖直接更新即可
   

2. nax-context 补充类型声明，实际上在 nav /index.tsx中已经通过 context往下传了 updateOpenKeys、addOpenKeys、removeOpenKeys三个操作函数，但因为之前代码中是通过 this._invokeContextFunc(isOpen ? 'addOpenKeys' : 'removeOpenKeys', this.props.itemKey 这种方式调用的，绕过了类型检测，所以并没有检测出类型缺失。

3. subNavFoundation中增加检测，如果hover时，这个 item已经是open状态，无论dropdown 由 show -> hide还是由 hide -> show，都不再修改 openKeys，解决 [Nav] in collapse mode hover item will lost open state which exist before collapse #2558 的问题
