Enforce a minimum of two arguments for wpdb::prepare(). The first argument is the query (or fragment thereof), which is required. Additional arguments are values to substitute into placeholders.

This will generate E_WARNINGs for insufficient arguments when prepare() is called with no additional arguments. This should discourage improper uses of prepare() under the guise of safely running a query.

props xknown. fixes #22262.
