Konstantin Knizhnik d5023f2b89 Restrict pump prefetch state only to regular backends (#12000) ...

## Problem

See https://github.com/neondatabase/neon/issues/11997

This guard prevents race condition with pump prefetch state (initiated
by timeout).
Assert checks that prefetching is also done under guard.
But prewarm knows nothing about it.

## Summary of changes

Pump prefetch state only in regular backends.
Prewarming is done by background workers now.
Also it seems to have not sense to pump prefetch state in any other
background workers: parallel executors, vacuum,... because they are
short living and can not leave unconsumed responses in socket.
