Rely on default test discovery.
Validation:
```bash
# Run before commit
./python -m test test_io -uall,walltime,largefile,cpu,extralargefile -M25G -o --fail-env-changed -j0 --list-cases | sort > old_cases.txt
# Run after commit
./python -m test test_io -uall,walltime,largefile,cpu,extralargefile -M25G -o --fail-env-changed -j0 --list-cases | sort > new_cases.txt
diff new_cases.txt old_cases.
# <outputs no changes in case list>
```
There was a deadlock originally seen by Memray when a daemon thread
enabled or disabled profiling while the interpreter was shutting down.
I think this could also happen with garbage collection, but I haven't
seen that in practice.
The daemon thread could be hung while trying acquire the global rwmutex
that prevents overlapping global and per-interpreter stop-the-world events.
Since it already held the main interpreter's stop-the-world lock, it
also deadlocked the main thread, which is trying to perform interpreter
finalization.
Swap the order of lock acquisition to prevent this deadlock.
Additionally, refactor `_PyParkingLot_Park` so that the global buckets
hashtable is left in a clean state if the thread is hung in
`PyEval_AcquireThread`.
Performance about the same, using the benchmark from gh-120754:
```
pyperf compare_to main.json pep782.json
read_file_small: Mean +- std dev: [main] 5.71 us +- 0.05 us -> [pep782] 5.68 us +- 0.05 us: 1.01x faster
read_file_large: Mean +- std dev: [main] 89.7 us +- 0.9 us -> [pep782] 86.9 us +- 0.8 us: 1.03x faster
read_all_rst_bytes: Mean +- std dev: [main] 926 us +- 8 us -> [pep782] 920 us +- 12 us: 1.01x faster
read_all_rst_text: Mean +- std dev: [main] 2.24 ms +- 0.02 ms -> [pep782] 2.17 ms +- 0.04 ms: 1.03x faster
Benchmark hidden because not significant (1): read_all_py_bytes
Geometric mean: 1.01x faster

Replace PyBytes_FromStringAndSize(NULL, size) with the new public
PyBytesWriter API.
Don't build the fcntl with the limited C API anymore, since
the PyBytesWriter API is not part of the limited C API.
The stack collector base class keeps all frames until export() is
called, which causes significant unnecessary memory usage. Instead, we
can process the frames on the fly in the collect call by dispatching the
aggregation logic to the subclass through the process_frames method.
