Tomasz Grabiec 3f03260ffb utils/chunked_managed_vector: Fix corruption in case there is more than one chunk ...

If reserve() allocates more than one chunk, push_back() should not
work with the last chunk. This can result in items being pushed to the
wrong chunk, breaking internal invariants.

Also, pop_back() should not work with the last chunk. This breaks when
there is more than one chunk.

Currently, the container is only used in the sstable partition index
cache.

Manifests by crashes in sstable reader which touch sstables which have
partition index pages with more than 1638 partition entries.

Introduced in 78e5b9fd85 (4.6.0)

Fixes #10290
