pgsql: Change BitmapAdjustPrefetchIterator to accept BlockNumber

Change BitmapAdjustPrefetchIterator to accept BlockNumber

BitmapAdjustPrefetchIterator() only used the blockno member of the
passed in TBMIterateResult to ensure that the prefetch iterator and
regular iterator stay in sync. Pass it the BlockNumber only, so that we
can move away from using the TBMIterateResult outside of table AM
specific code.
