…rned strings. (pythongh-124646)"

This reverts commit dc09a0c.

The pythongh-124646 fix has the issue that it breaks the trace-refs debug
build.  This is a simpler fix that avoids the use-after-free crashes by
just leaking immortal interned strings allocated by legacy
subinterpreters.

Fix a crash caused by immortal interned strings being shared between
sub-interpreters that use basic single-phase init. In that case, the string
can be used by an interpreter that outlives the interpreter that created and
interned it. For interpreters that share obmalloc state, also share the
interned dict with the main interpreter.

This is an un-revert of gh-124646 that then addresses the Py_TRACE_REFS
failures identified by gh-124785.
