* Report errors from #[pyclass] trait items
The trait branch of impl_pyclass_impl built its own ImplContext, so the
errors collected while extracting trait items were never emitted: an
invalid #[pymethod] or #[pygetset] in a #[pyclass] trait was left out of
the class without a compile error. The trait branch now uses the shared
context whose errors are emitted.

* Pass the object to #[pymethod] and #[pygetset] receivers outside vm
Outside crates/vm, where impl Py<T> cannot be written, #[pymethod] and
#[pygetset] receivers that took &self become zelf: &Py<Self> inside the
existing impl T blocks. Where Rust code calls one of these methods on a
payload value, the logic stays in a payload method and the Python method
forwards to it.

* Reject payload receivers on #[pymethod] and #[pygetset]
A #[pymethod] or #[pygetset] item with a self receiver is now a compile
error when self is the payload: in an impl for T rather than Py<T> or
PyRef<T>, and in a #[pyclass] trait. The error points to taking
zelf: &Py<Self> or zelf: PyRef<Self>, or defining the item in impl Py<T>.

* Pass the object to the layout test getter
The subclass layout test's extra getter is a #[pygetset] on the

* Borrow tp_descr_get/tp_init arguments and by-value public helpers
- DescrGetFunc and GetDescriptor::descr_get take
(&PyObject, Option<&PyObject>, Option<&PyObject>); impls call
.to_owned() where they store or return an argument.
- InitFunc takes &PyObject and Initializer::init takes &Py<Self>.
- VirtualMachine::get_attribute_opt, print_exception,
call_get_descriptor(_specific) and other helpers flagged by
clippy::needless_pass_by_value take &PyObject / &Py<T>; callers in
crates/, examples/ and tests/ drop the clones made for the call.

* ssl: read the OID table out of OpenSSL's object database
`txt2obj` and `nid2obj` have to answer with OpenSSL's own numbers, and the
table behind them was 39 entries transcribed by hand, so every object
outside that set was reported unknown.
Read OpenSSL's own files instead: `obj_mac.num` carries each object's NID
and `objects.txt` carries its OID, short name and description, and the
identifier `objects.pl` derives per object -- the `!Cname` override, else
the description, else the short name, each qualified by the enclosing
`!module` with `-` spelled `_` -- joins the two. `OidEntry`, `OidTable`
and the `find_by_*` functions keep their shape, so `ssl.rs` only changes
where an object has no OID to report.
Three details the object database settles that a curated table did not
have to:
- an object written with one name carries it as both, so
`nid2obj(48)` is `('emailAddress', 'emailAddress', ...)`;
- an object need not have an OID at all -- `DES-EDE3` and 139 other
algorithm names have a NID and nothing to encode -- so the fourth
field of the tuple is None for those, as it is on OpenSSL;
- one arc does not encode, since DER packs the first two into a byte,
so the bare roots `iso` and `itu-t` are OID-less too, while two arcs
such as X500's `2.5` are a real object.
Checked against `_ssl.nid2obj` on CPython built with OpenSSL, over every
NID it answers: 1387 of its 1390 present, with no disagreement on any of
them, up from 39. The three absent are OpenSSL's unnamed placeholder
slots, which it reports as ('NULL', 'NULL', None).
The data files come from openssl/openssl `crypto/objects/`, via the
rustls integration rewrite in #8007.

* ssl: parse OpenSSL cipher strings in set_ciphers
Replaces the pattern matcher `set_ciphers` used with the grammar
`man openssl-ciphers` documents, in a new `ssl/cipher.rs` taken from
#8007: `!`, `-`, `+`, `@STRENGTH`, `@SECLEVEL=n`, `+`-joined
conjunctions, the DEFAULT/ALL/COMPLEMENTOF* groups, protocol versions,
SUITEB*, and the aXXX/kXXX/eXXX prefixes.
`set_ciphers` raises "No cipher can be selected." for a string that
names nothing the provider offers, which is the one failure
SSL_CTX_set_cipher_list reports, and keeps the TLS 1.3 suites selected
in provider order because that setter does not reach them. A SUITEB*
string pins its own key exchange groups, which `prepare_kx_groups`
now reads.
Against CPython's OpenSSL over 78 cipher strings, the selections agree
except under `@SECLEVEL=n`, which OpenSSL applies at handshake time and
this applies to the selection.
`CryptoExt` gains `default_cipher_suites` so that `DEFAULT` and `ALL`
are distinguishable.

* ssl: finish cipher reporting and provider handling
Use the provider-ordered cipher metadata table as the single source for parsing, reporting, OpenSSL names and descriptions. This makes get_ciphers reflect the context selection and validates curves and Suite B against the active provider.
Keep set_ciphers from changing TLS 1.3 suites, preserve the provider's order, fix empty conjunctions, and keep FIPS initialization within the provider's filtered cipher and key-exchange defaults.

* Modularize rustls as work towards providers
`rustls`'s architecture is very clean and trait-driven. There are many
providers for `rustls` including the built-in `aws-lc-rs` and `ring` as
well as backends for `boringssl`, `graviola`, `openssl`, `mbedtls`, etc.
This commit removes the hard dependency on `aws-lc-rs` and adds support
for `ring`. It works towards #7059 as well.
* Clean up rustls features
* Remove ring as an explicit feature
* ssl-rustls is the default and implies aws-lc
* Support custom rustls crypto providers
The new feature, `ssl-rustls-no-provider`, enables custom rustls
providers. By default, `aws-lc-rs` is enabled which matches the old
behavior and keeps backward compatibility.
I wrote a new type that abstracts what we need from crypto providers.
CryptoExt encapsulates the ticketer as well as cipher suites and KX
groups. I wrote fallbacks to help select a reasonable default if a
provider is missing features (they all seem to support the same things
though).
I also wrote an example to show how to actually use custom providers.
* Fix duplicate VERIFY_X509 constants and unused imports in ssl module
Remove duplicate VERIFY_X509_STRICT/VERIFY_X509_PARTIAL_CHAIN definitions
from compat.rs (already defined in _ssl module with #[pyattr]).
Remove unused imports: ClientConnection, ServerConnection.
* no-provider as default
* Fix CI failures: openssl build, wasm target, cargo-shear
- Update openssl.rs to use renamed sock_wait/SockWaitKind and add vm parameter
- Add skip_ssl for wasm32-wasip2 target (aws-lc-sys cannot build for wasm)
- Remove unused workspace dependency aws-lc-rs
- Fix foreign-types-shared version to match openssl's dependency (0.1)
- Restore Cargo.lock from upstream/main
