For master (8.4-dev) I merged GH-13381. But that PR changes public API of TSRM, so cannot be used on lower branches. This patch is a safe workaround for the issue, in combination with a pre-existing fix using `ifdef ZTS + if (module_started)` inside pgsql and odbc. The idea is to delay unloading modules until the persistent resources are destroyed. This will keep the destructor code accessible in memory. This is not a proper fix on its own, because we still need the workaround of not accessing globals after module destruction. The proper fix is in master. Closes GH-13388.
