John Spray 5667372c61 pageserver: during shard split, wait for child to activate (#6789) ...

## Problem

test_sharding_split_unsharded was flaky with log errors from tenants not
being active. This was happening when the split function enters
wait_lsn() while the child shard might still be activating. It's flaky
rather than an outright failure because activation is usually very fast.

This is also a real bug fix, because in realistic scenarios we could
proceed to detach the parent shard before the children are ready,
leading to an availability gap for clients.

## Summary of changes

- Do a short wait_to_become_active on the child shards before proceeding
to wait for their LSNs to advance
