Support arbitrary number of arguments for d:or and d:and in search queries

The sabredav plugin already handles this case, just have to properly transform it to the db query

See #3360 (comment)

Hello All, I would like to understand how PR's like this end up in a release. Does the `Nextcloud 14` milestone set to this PR indeed mean, it will be in 14.0? Or is there still a change that it will be sooner. I am not in a hurry, but I am interested to understand how you guys plan the project around git. Thanks! Barry

There is already a backport to stable13 approved and will be included in 13.0.0 😉 See #7883 for the backport
