Reuse BrinDesc and BrinRevmap in brininsert

Browse Source 
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).
