ext/odbc: document the row default value change to null in fetch_object/array/into (PHP 8.4)

[lacatoire]

The changelog rows of odbc_fetch_object(), odbc_fetch_array() and odbc_fetch_into() state only that row became nullable in PHP 8.4.0. They omit the accompanying change of default value, which is the part that changes behaviour for existing calls: the previous defaults -1 and 0 were row positions, whereas null means "fetch the next row", the semantics odbc_fetch_row() already had.

8.3.0  odbc_fetch_array($statement, int $row = -1): array|false
8.3.0  odbc_fetch_into($statement, &$array, int $row = 0): int|false
8.3.0  odbc_fetch_row($statement, ?int $row = null): bool

8.4.0  odbc_fetch_object($statement, ?int $row = null): stdClass|false
8.4.0  odbc_fetch_array($statement, ?int $row = null): array|false
8.4.0  odbc_fetch_into($statement, &$array, ?int $row = null): int|false
8.4.0  odbc_fetch_row(Odbc\Result $statement, ?int $row = null): bool

The parameter descriptions need to be aligned as well

Looks good to me, but I think you have to fix the simparas.
