Cleanup some direct magic method definitions by moreal · Pull Request #7441 · RustPython/RustPython

Move #[pymethod] __del__ to impl Destructor for PySocket.
Preserves ResourceWarning emission and close behavior.

Both types already have impl Iterable, so the direct #[pymethod]
__iter__ definitions were duplicates. Enable __iter__/__next__
guards in derive to prevent future direct definitions.

All concrete types already use GetDescriptor/SetDescriptor traits.
Activate the compile-time guard to prevent future direct definitions.

Remove redundant #[pymethod(name = "__len__")] from PyStr
(already provided via AsMapping/AsSequence trait impls).

Enable compile-time guards for __len__, __contains__, __getitem__,
__setitem__, __delitem__ to prevent future direct definitions.

* Migrate direct __repr__ definitions to Representable trait

Move legacy #[pymethod] __repr__ to impl Representable for:
- PySSLContext, PySSLSocket (ssl.rs)
- BufferedReader, BufferedWriter, BufferedRandom (_io.rs)

Enable __repr__ guard in derive to prevent future direct definitions.
