 {{{
 #!CommitTicketReference repository="" revision="29887"
 Introduce support for nested queries in WP_Meta_Query.

 Previously, meta query arguments could be joined by a single AND or OR
 relation.
 Now, these queries can be arbitrarily nested, allowing clauses to be
 linked
 together with multiple relations.

 Adds unit tests for the new nesting syntax. Modifies a few existing unit
 tests
 that were overly specific for the old SQL syntax. Backward compatibility
 with
 existing syntax is fully maintained.

 Props boonebgorges, DrewAPicture.
 See #29642.
