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.
