✨ [Feature]: Hope to add the TypeScript type declaration of components

[kagol]

What problem does this feature solve

Adding type declaration to components can improve the developer experience(DX).

建议优先完善高频组件的 TypeScript 类型声明。

TinyVue 高频组件

What does the proposed API look like

Take the alert component as an example.

packages/renderless/src/alert/vue.ts

  // Add type declaration to state
  const state: IAlertState = reactive({
    show: true,
    getIcon: computed(() => api.computedGetIcon()),
    getTitle: computed(() => api.computedGetTitle()),
    contentVisible: false,
    contentDescribeHeight: 0,
    contentDefaultHeight: 0,
    contentMaxHeight: constants.CONTENT_MAXHEUGHT,
    scrollStatus: false
  })

export interface IAlertState {
  show: boolean
  getIcon: ComputedRef<string>
  getTitle: ComputedRef<string>
  contentVisible: boolean
  contentDescribeHeight: number
  contentDefaultHeight: number
  contentMaxHeight: number
  scrollStatus: boolean
}

The TypeScript type declaration of the component needs to be continuously improved.
