Fix race condition in grpc_shutdown causing use-after-free in c-ares
Testing CI with shutdown order fix.
This PR swaps the order of grpc_iomgr_shutdown() and grpc_resolver_dns_ares_shutdown()
in grpc_shutdown_internal_locked() to prevent race condition.
**Root Cause:**
- Timer destructors (~grpc::Alarm) call grpc_timer_cancel()
- Parallel grpc_shutdown() frees c-ares resources
- Results in use-after-free
**Fix:**
Stop timers (grpc_iomgr_shutdown) BEFORE freeing c-ares (grpc_resolver_dns_ares_shutdown).
