feat: migrate to web components API

* Based on nextcloud/server#50783
* For #514
  * Server companion: nextcloud/server#54788
  * Library companion: nextcloud-libraries/nextcloud-sharing#95

We  need to provide an API that does not rely on Vue.
As Vue components **must not** be shared between different apps.
