Konstantin Knizhnik 8eb701d706 Save FSM/VM pages on normal shutdown (#11449) ...

## Problem

See https://neondb.slack.com/archives/C03QLRH7PPD/p1743746717119179

We wallow FSM/VM pages when they are written to disk to persist them in
PS.
But it is not happen during shutdown checkpoint, because writing to WAL
during checkpoint cause Postgres panic.

## Summary of changes

Move `CheckPointBuffers` call to `PreCheckPointGuts`
