Subject: Fix #79664: PDOStatement::getColumnMeta fails on empty result set

As its name suggests, `sqlite3_data_count` returns the number of
columns in the current row of the result set; we are interested in the
number of columns regardless of the current row, so we have to use
`sqlite3_column_count` instead.
