FEATURE: add advanced order to search (#10385)

Browse Source 
Similar to `advanced_filter` I introduced `advanced_order`.

I needed a new option because default orders are evaluated after advanced_filter so I couldn't use it.

Also, that part is a little bit more generic
```
elsif word =~ /order:\w+/
  @order = word.gsub('order:', '').to_sym
nil
```

After those changes, I can use them in plugins in this way:
```
Search.advanced_order(:votes) do |posts|
  posts.reorder("COALESCE((SELECT dvvc.counter FROM discourse_voting_vote_counters dvvc WHERE dvvc.topic_id = subquery.topic_id), 0) DESC")
end
```
