Add multiple order conditions to WP_Term_Query

[oglekler]

Now WP_Term_Query accepts orderby only as a string, as WP_Query accepts an array.

Use case: I need to sort by term meta plus title. I cannot sort after getting the terms because I am not getting meta with terms, and requesting meta for each term will be unproductive.

Thanks, @oglekler, for the enhancement suggestion.

I observed the WP_Query structure closely and attempted to replicate something similar with the WP_Term_Query. I have tested all edge cases as much as I could. I'm gonna go ahead and add the needs-testing label so that others can also take a swing at this and see if this breaks anything else while I am preparing automated tests for this.
