enhance: Use ListIndexes instead of DescribeIndex for qc broker (#31122)
See also #31103

Since querycoord need index meta information from datacoord only, broker
shall use `ListIndexes` to skip segment index building check logic in
datacoord

This PR is also related to #30538, in which DescribeIndex caused lots of
memory usage and lead to OOM eventually
