Pablo Galindo Salgado 072cd7c336 gh-142349: Fix refcount corruption in lazy import specialization (#144733 )

Remove spurious Py_DECREF on borrowed ref in LOAD_GLOBAL specialization

_PyDict_LookupIndexAndValue() returns a borrowed reference via
_Py_dict_lookup(), but specialize_load_global_lock_held() called
Py_DECREF(value) on it when bailing out for lazy imports. Each time
the adaptive counter fired while a lazy import was still in globals,
this stole one reference from the dict's object. With 8+ threads
racing through LOAD_GLOBAL during concurrent lazy import resolution,
enough triggers accumulated to drive the refcount to zero while the
dict and other threads still referenced the object, causing
use-after-free.
