What problem does this feature solve

现状是当我配置 icon 时，输入框中未能显示选中项，这不符合我的预期。

What does the proposed API look like

我看 Select 目前已有 label 的插槽，但是没有在 api 表格文档中体现。而且该插槽存在以下问题：

目前只支持多选场景（配置了 multiple 才生效，参考 demo 锚点标签）
只暴露了 value、label，没有暴露icon等其他属性

期望 label 插槽支持单选场景、并且暴露所有用户配置的属性，包括 icon 等。

大致用法如下：

const options = ref([
  { value: '选项1', label: '北京', icon: iconFile() },
  { value: '选项2', label: '上海', icon: iconAttachment() },
  { value: '选项3', label: '广州', icon: iconPublish() },
  { value: '选项4', label: '深圳', icon: iconSmile() }
])

<tiny-select v-model="selectValue">
  <template #label="{ item }">
    <component :is="item.icon" />
    <span>{{ item.label }}</span>
  </template>
  <tiny-option v-for="mail in mailList" :value="mail.value" :label="mail.label" :icon="mail.icon"></tiny-option>
</tiny-select>
