Fix #66021 (Blank line inside empty array/object)

Changed json_encode() so that when the JSON_PRETTY_PRINT option is specified,
the pair of linefeeds immediately after an opening bracket and before the
corresponding closing bracket is omitted when the array or object contains no
elements or accessible properties (and hence would have a blank line between
the brackets).

New result fetching mode for mysqlnd, which should use less memory but
implies more memory copy. The old method is still available and can be used.
It stays as default. Choosing the method is through a flag to mysqli_query()/mysqli_real_query()
New mode can be forced with an INI setting, for all extensions that support this mode
(ext/mysql and mysqli, because PDO due to it's architecture can't support it)
The setting is mysqlnd.fetch_data_copy=[0|1]
