(cherry picked from commit c21113072c)

The `test_ssl_in_multiple_threads` test failed because `test_check_hostname_idn()`
modified the global warnings filters via `warnings_helper.check_no_resource_warning()`.
Only check for warnings when the context aware warnings feature is enabled, which makes
the warnings filter context-local and thread-safe.

On Windows, the `_PyOS_SigintEvent()` event handle is used to interrupt
the main thread when Ctrl-C is pressed. Previously, we also waited on
the event from other threads, but ignored the result. However, this can
race with interpreter shutdown because the main thread closes the handle
in `_PySignal_Fini` and threads may still be running and using mutexes
during interpreter shtudown.
Only use `_PyOS_SigintEvent()` in the main thread in parking_lot.c, like
we do in other places in the CPython codebase.

On a fresh Xcode install (including some CI provider configurations), there is
no pre-existing testing set that can be used to identify simulator models. Use
the default device set to detect available models instead. Live testing
simulators are still created in the testing set.

gh-134248 test_getallocatedblocks pre-check to ignore immortalized strings (GH-134871)
When sanity checking against gettotalrefcount(), we exclude the blocks for
immortalized strings since their references are not tracked/reported. This
now matches refleak.py's book-keeping using the same functions.
