Do not perform prefetch for temp relations (#10146)

Browse Source 
## Problem

See https://neondb.slack.com/archives/C04DGM6SMTM/p1734002916827019

With recent prefetch fixes for pg17 and `effective_io_concurrency=100` 
pg_regress test stats.sql is failed when set temp_buffers to 100.
Stream API will try to lock all this 100 buffers for prefetch.

## Summary of changes

Disable such behaviour for temp relations.
