Build fails due to custom directive missing an SSR Transform

Describe the bug

Adding a simple directive inside a markdown file or an SFC throws an error during the build. Seems like ClientOnly component does not exist yet in VitePress.

Custom directive is missing corresponding SSR transform and will be ignored.

To Reproduce

<div v-test>test</div>


<script>
export default {
  directives: {
    test: {
      mounted(el, binding) {
        console.log(el)
      }
    }
  }
}
</script>

Expected behavior Build should work even though an SSR implementation for the custom directive doesn’t exist.

System Info

• vitepress version: 0.6.0
• vite version: v1.0.0-rc.4
• Node version: 12.18.3
• OS version: Catalina 10.15.6

Additional context None.

v3 SSR docs are not fully complete yet, so for now you’ll have to read the types here: https://github.com/vuejs/vue-next/blob/master/packages/compiler-core/src/transform.ts#L56

ClientOnly is implemented in 8809d2d and will be available in the next release.
