pgsql: Fix BRIN 32-bit counter wrap issue with huge tables

Fix BRIN 32-bit counter wrap issue with huge tables

A BlockNumber (32-bit) might not be large enough to add bo_pagesPerRange
to when the table contains close to 2^32 pages. At worst, this could
result in a cancellable infinite loop during the BRIN index scan with
power-of-2 pagesPerRange, and slow (inefficient) BRIN index scans and
scanning of unneeded heap blocks for non power-of-2 pagesPerRange.

Backpatch to all supported versions.
