sql: update crdb_internal.interleaved to be more usable

Previous, when we added the crdb_internal.interleaved table that
showed all interleaved indexes, however it was impossible tell
which table the primary key of the parent table was interleaved.
This was inadequate because users could not tell what the parent
table was. To address this, this patch modifies
crdb_internal.interleaved to add a parent_table_name column
replacing the parent_index one, since that column could only be
the primary key.

Release note (sql change): Updated crdb_internal.interleaved to
add the parent_table_name column replacing the parent_index_name
column.
