The brininsert code used to initialize (and destroy) BrinDesc and BrinRevmap for each tuple, which is not free. This patch initializes these structures only once, and reuses them for all inserts in the same command. The data is passed through indexInfo->ii_AmCache. This also introduces an optional AM callback "aminsertcleanup" that allows performing custom cleanup in case simply pfree-ing ii_AmCache is not sufficient (which is the case when the cache contains TupleDesc, Buffers, and so on).
