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.

Use assertEqualSets() for a few taxonomy-related tests.

assertEquals() was causing problems in environments where the tests take more
than one second to run, thereby causing results to be returned in the incorrect
order.
