Logic sensor (#10795)

* Add `selectedBlock` logic sensor

* Add `buildX`/`buildY`/`building` logic sensors

* Change `building` from boolean to the building

* `breaking`

* Make `breaking`/`building` more consistent

* Allow blocks/content to be null

* Change `selectedBlock` from air to null

* Change `selectedBlock` from air to null

* Make `selectedBlock` SyncLocal

* Add `selectedRotation`
