fix: trigger close only when click wrap itself

[kerm1it]

fix ant-design/ant-design#28353
fix ant-design/ant-design#28399

在 ant-design/ant-design#28353 中，点击 label 中的元素，label 会连续触发两次点击事件，冒泡到父级弹窗的时候，由于父子弹窗没有包含的关系，就会触发父级的关闭事件。

在 ant-design/ant-design#28399 是因为在下拉框中的触发点击事件，冒泡了上来，但是下拉框和弹窗没有包含关系，也会触发关闭事件。

dialog/src/Dialog/index.tsx

Line 115 in 4c3b871

!contains(contentRef.current.getDOM(), e.target as HTMLElement)

这里的逻辑其实就是只要不是点击的内容就触发关闭，在弹窗中 wrap 是撑满屏幕，不点击内容就是点击 wrap 本身，刚好规避了上述两种特殊情况

@zombieJ 评估一下，有没有副作用。
