Tomas Vondra 19d8e2308b Ignore BRIN indexes when checking for HOT updates
When determining whether an index update may be skipped by using HOT, we
can ignore attributes indexed by block summarizing indexes without
references to individual tuples that need to be cleaned up.

A new type TU_UpdateIndexes provides a signal to the executor to
determine which indexes to update - no indexes, all indexes, or only the
summarizing indexes.

This also removes rd_indexattr list, and replaces it with rd_attrsvalid
flag. The list was not used anywhere, and a simple flag is sufficient.

This was originally committed as 5753d4ee32, but then got reverted by
e3fcca0d0d because of correctness issues.

Original patch by Josef Simanek, various fixes and improvements by Tomas
Vondra and me.
