* Implement termios.tcgetwinsize/tcsetwinsize
Adds ioctl(TIOCGWINSZ/TIOCSWINSZ) wrappers in host_env and the
corresponding Python-facing functions in the termios stdlib module,
removing the associated expectedFailure markers in test_termios.py.

* Use ret < 0 convention for ioctl error checks in termios winsize
POSIX ioctl only guarantees -1 on failure, not exactly 0 on success;
matches the existing check_libc_neg convention used elsewhere in
host_env (e.g. fcntl.rs, posix.rs::get_terminal_size).

* Reject non-sequence size in tcsetwinsize
extract_elements_with also accepted dicts (treating keys as elements).
Switch to try_sequence(), matching CPython's PySequence_Check, so only
real sequences (tuple/list/etc.) are accepted.

* Use `core::mem::zeroed` instead of `std::mem::zeroed`
`std::mem` just re-exports `core::mem`, but clippy prefers importing
from core when there's no OS dependency. This was breaking the wasm CI build.

* Use try_index for tcsetwinsize row/col conversion
CPython's PyLong_AsLong calls __index__ on non-int objects before
converting, so downcast_ref::<PyInt> was stricter than CPython.
try_index matches that behavior and is more concise.

* Mark test_fork/test_spawn_doesnt_hang as expected failures
Both were hidden by a skipIf on tty.tcgetwinsize, which now exists.
Root cause: pty.fork() calls os.login_tty(), which isn't implemented,
so the forked child crashes before the test body runs.

* Use unittest.skip instead of expectedFailure for pty.fork() tests
expectedFailure still runs the test body, so pty.fork()'s real fork()
still happens and the child crashes on missing os.login_tty inside the
parallel test runner's worker process, corrupting its JSON reporting
channel ("worker bug"). skip prevents the method from running at all,
avoiding that. Verified locally with -j 2.
