Store stripe_size in shared memory (#12560)

Browse Source 
## Problem

See https://databricks.slack.com/archives/C09254R641L/p1752004515032899

stripe_size GUC update may be delayed at different backends and so cause
inconsistency with connection strings (shard map).

## Summary of changes

Postmaster should store stripe_size in shared memory as well as
connection strings.
It should be also enforced that stripe size is defined prior to
connection strings in postgresql.conf
