Docs: Improve first-order clause documentation for the `$meta_query` parameter in the constructor for `WP_Meta_Query`. 

First-order meta query clauses are defined as clauses that have either a 'key' or 'value' array key. When using named first-order clauses in meta queries to order results in the parent query, `WP_Meta_Query` can additionally accept first-order clauses at the sub-clause level, which was not previous documented.

Fixes #32659.
