Add CHECK_FOR_INTERRUPTS in Evict{Rel,All}UnpinnedBuffers.
This commit adds CHECK_FOR_INTERRUPTS to the shared buffer iteration
loops in EvictRelUnpinnedBuffers and EvictAllUnpinnedBuffers. These
functions, used by pg_buffercache's pg_buffercache_evict_relation and
pg_buffercache_evict_all, can now be interrupted during long-running
operations.
Backpatch to version 18, where these functions and their corresponding
pg_buffercache functions were introduced.
