Benny Halevy a57c087c89 atomic_cell: compare_atomic_cell_for_merge: compare ttl if expiry is equal
Unlike atomic_cell_or_collection::equals, compare_atomic_cell_for_merge
currently returns std::strong_ordering::equal if two cells are equal in
every way except their ttl:s.

The problem with that is that the cells' hashes are different and this
will cause repair to keep trying to repair discrepancies caused by the
ttl being different.

This may be triggered by e.g. the spark migrator that computes the ttl
based on the expiry time by subtracting the expiry time from the current
time to produce a respective ttl.

If the cell is migrated multiple times at different times, it will generate
cells that the same expiry (by design) but have different ttl values.

Fixes #10156

Test: mutation_test.test_cell_ordering, unit(dev)
