[Feature Request] add new Block component

[anonimusprogramus]

What problem does this feature solve?

A neat and proper div is commonly used, imho van should provide one to make our life easier :smile:

The reason is that vant is actually already using it in demo :+1:

What does the proposed API look like?

  <demo-block :title="t('type')">
    <div class="demo-button-row">
      <van-button type="primary">{{ t('primary') }}</van-button>
      <van-button type="success">{{ t('success') }}</van-button>
      <van-button type="default">{{ t('default') }}</van-button>
    </div>
    <van-button type="danger">{{ t('danger') }}</van-button>
    <van-button type="warning">{{ t('warning') }}</van-button>
  </demo-block>
