Card: customizable close button

[OrbisK]

This function solves the problem (这个功能解决的问题)

currently it is not possible to use an other icon or another kind of button as close button. (without overriding header-extra)

Expected API (期望的 API)

<n-card
    :close-button-props="{round: true}",
    :render-close-icon="()=>h(NIcon, {}, ()=>h(MyFunnyIcon))">
...
</n-card>

or

<n-card
    :close-button-props="{round: true}",
>
    <tempalte #closeIcon>
        <n-icon><MyFunnyIcon></n-icon>
    </template>
</n-card>
