Fix dependency handling at swap phase of REINDEX CONCURRENTLY
When swapping the dependencies of the old and new indexes, the code has
been correctly switching all links in pg_depend from the old to the new
index for both referencing and referenced entries. However it forgot
the fact that the new index may itself have existing entries in
pg_depend, like references to the parent table attributes. This
resulted in duplicated entries in pg_depend after running REINDEX
CONCURRENTLY.
Fix this problem by removing any existing entries in pg_depend on the
new index before switching the dependencies of the old index to the new
one. More regression tests are added to check the consistency of
entries in pg_depend for indexes, including partition indexes.
