Sergey Zolotukhin 13392a40d4 gossiper: check for a race condition in do_apply_state_locally
In do_apply_state_locally, a race condition can occur if a task is
suspended at a preemption point while the node entry is not locked.
During this time, the host may be removed from _endpoint_state_map.
When the task resumes, this can lead to inserting an entry with an
empty host ID into the map, causing various errors, including a node
crash.

This change adds a check after locking the map entry: if a gossip ACK update
does not contain a host ID, we verify that an entry with that host ID
still exists in the gossiper’s _endpoint_state_map.

Fixes scylladb/scylladb#25702
Fixes scylladb/scylladb#25621

For details on how to run the tests, see docs/dev/testing.md

Shared C++ utils, libraries are in lib/, for Python - pylib/

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.
