Make sure the keys are full prefixes as it is expected to be the case for rows. At severeal occasions we have seen empty row keys make their ways into the sstables, despite the fact that they are not allowed by the CQL frontend. This means that such empty keys are possibly results of memory corruption or use-after-{free,copy} errors. The source of the corruption is impossible to pinpoint when the empty key is discovered in the sstable. So this patch adds checks for such keys to places where mutations are built: when building or unserializing mutations.
Fixes: https://github.com/scylladb/scylladb/issues/24506
Not a typical backport candidate (not a bugfix or regression fix), but we should still backport so we have the additional checks deployed to existing production clusters.

If you can use an existing folder, consider adding your test to it. New folders should be used for new large categories/subsystems, or when the test environment is significantly different from some existing suite, e.g. you plan to start scylladb with different configuration, and you intend to add many tests and would like them to reuse an existing Scylla cluster (clusters can be reused for tests within the same folder).
To add a new folder, create a new directory, and then
copy & edit its suite.ini.
