Fix ht corruption during shutdown for bailing user stream

Fixes GH-19844

This looks hacky and will likely cause leaks for resources that were not yet destroyed.

I'm not sure there are any good solutions for bailout during shutdown. We might minimize leaking by wrapping each resource destructor call in zend_try. I'm open to suggestions.

Also note that it at least does not introduce any new leaks. The current code would already leak if the second attempt to call the destructor bails again.

I agree this is better than before, and this is similar to how we handle bailouts in shutdown_destructors(). However there is more risk of leaking scarce resources (file descriptors) in this case than with destructors, so it may be worth it to try to release them anyway. zend_close_rsrc_list() could wrap the entire loop in zend_try and restart to the next resource after a bailout.

Okay, I adjusted the code to keep closing resources even after bailout, so that the resources don't leak.
