[#23215] docdb: disable packed for colocated tables by default

Summary:
Packed + colocated + restore can cause corruption of tablet schema packings: #23047
We are disabling the feature for now, will re-enable it when #23047 is fixed

`ysql_enable_packed_row_for_colocated_table` is on by default only in master, so it's sufficient to only land this diff to master.
