[20816] Properly delete builtin statistics writers upon `delete_contained_entities()` (backport #4891)

[mergify[bot]]

Description

This PR fixes a wrong behavior that occurs when closing an application making an intensive use of statistics. If in the shutdown pipeline, after a manual removal of entities (delete_datareader, delete_subscriber, delete_topic) if delete_contained_entities() was called, it caused a race when alive endpoints try to keep using the statistics builtin endpoints (writers).

@Mergifyio backport 2.14.x 2.13.x 2.10.x 2.6.x
