more hostenv isolation (#7886)

Browse Source 
* Convert host_env Windows path/argv params from raw *const u16 to &WideCStr

* Migrate remaining winapi raw u16 pointer signatures to typed references

* Migrate winreg pub unsafe fn string parameters to typed references

* Add ToPyException impls for host_env error types (PyPy wrap_oserror analog)

* Add CheckLibcResult helper and apply to socket/fcntl/shm/posix_wasi

* Add Win32 BOOL/HANDLE check helpers; apply check helpers across host_env

* Apply Win32/libc check helpers to overlapped/testconsole/os.rs

* Apply Win32 check helpers to winapi.rs (partial)

* Apply Win32 check helpers across more winapi.rs functions

* Apply Win32 check helpers to nt.rs (partial)

* Add CheckWin32Sentinel helper; apply to nt.rs INVALID_HANDLE_VALUE/INVALID_FILE_ATTRIBUTES patterns

* Add OwnedHandle / HandleToOwned helper; apply to mmap create_named_mapping leak path

* Use OwnedHandle RAII in nt::pipe to eliminate manual cleanup on error path

* Use OwnedHandle in nt::chmod_follow; hoist HandleToOwned import

* Drop rustix dependency from vm crate

Remove unused IntoPyException impl for rustix::io::Errno and the
rustix entry in crates/vm/Cargo.toml. rustix is now only depended on
by host_env.

* Fix CI failures: cross-platform regressions

- winapi.rs: pass None to create_event_w; the recent Option<&WideCStr>
  migration left one call site still passing a raw null pointer.
- exceptions.rs: gate ToPyException for LockfError with
  cfg(any(unix, target_os = "wasi")), matching host_env::fcntl's own
  cfg. The previous cfg let it compile on wasm32-unknown-unknown where
  host_env::fcntl does not exist.
- io_unsupported.rs: derive Eq on FileMode alongside PartialEq to
  satisfy clippy::derive_partial_eq_without_eq.

* Fix CI failures: cfg gates and unused imports

- exceptions.rs: gate ToPyException for LockfError with
  cfg(all(unix, not(target_os = "redox"))) to match the type's own
  cfg in host_env/src/fcntl.rs (LockfError is not built on wasi).
- signal.rs: CheckLibcResult is only used in unix-gated functions;
  split import so it is not pulled in for windows.
- mmap.rs: remove CheckWin32Handle from imports; no longer used after
  switching to HandleToOwned-based RAII.
- overlapped.rs: remove INVALID_HANDLE_VALUE from connect_pipe import;
  the call now uses .check_valid().

* Fix CI failures: rustfmt and windows unused import

- signal.rs: reorder cfg-gated imports per rustfmt.
- socket.rs: gate ToPyException import to cfg(all(unix, not(target_os = "redox")));
  it is only used inside sendmsg which has the same gate, so it was unused
  on windows.

* Push remaining libc/extern callsites from vm into host_env

Add host_env wrappers and replace the corresponding vm call sites:
- host_env::errno::strerror_string for libc::strerror
- host_env::io::write_stderr_raw for libc::write(STDERR_FILENO,...)
- host_env::locale::localeconv_data reused from vm::format
- host_env::os::abort for the inline abort extern
- host_env::os::urandom wraps getrandom; getrandom moves from vm to host_env
- host_env::posix::lchmod for the macOS/BSD lchmod extern
- host_env::posix::fcopyfile for the macOS fcopyfile extern
- host_env::nt::wputenv for the Windows _wputenv extern

vm/format.rs's get_locale_info now uses host_env on both unix and windows
instead of the unix-only libc::localeconv path.

* Move time tz state and winsound FFI into host_env

- host_env::time::tz: wraps the libc tzset/timezone/daylight/tzname
  globals on non-msvc, non-wasm32 targets. vm::stdlib::time now reads
  these via the typed wrappers instead of declaring its own externs.
- host_env::winsound (windows): exposes PlaySoundW (via a typed
  PlaySoundSource enum), Beep, and MessageBeep. vm::stdlib::winsound
  drops its inline FFI block and routes through host_env.

* Migrate unsetenv to host_env::nt::wputenv; rustfmt

- vm::stdlib::os::unsetenv had a second _wputenv call site that still
  referenced the removed inline extern. Route it through
  host_env::nt::wputenv like putenv.
- rustfmt fixups in exceptions.rs (boolean chain layout) and the two
  winsound files.

* Address PR review comments

- host_env::winapi::create_process: assert that the command_line buffer
  is NUL-terminated and that the env block ends with a double-NUL,
  matching the Win32 CreateProcessW contract.
- stdlib::overlapped CreateEvent: replace WideCString::from_str_truncate
  with the fallible from_str(), so embedded NULs in the event name
  surface as ValueError instead of being silently truncated.
- vm::exceptions::ReadlinkError::NotSymbolicLink now maps to OSError
  (matches Win32 ERROR_NOT_A_REPARSE_POINT semantics) rather than
  ValueError.
- winreg::ConnectRegistry: route the non-zero return through the
  existing os_error_from_windows_code helper so the resulting exception
  carries the real winerror/message instead of a generic OSError.

* Fix CI failures and address review follow-ups

CI failures:
- rustfmt cleanup in exceptions.rs after the ReadlinkError change.
- vm/stdlib/os.rs: drop unused ToWideString import that the wputenv
  migration left behind.
- vm/stdlib/winsound.rs: replace explicit `&*buf` with `&buf` to
  satisfy clippy::explicit_auto_deref.
- Lib/test/test_format.py, Lib/test/test_types.py: drop the now-stale
  expectedFailureIfWindows decorators on the locale-format tests; the
  Windows path now reads real `localeconv` data via host_env so these
  tests pass.

Review follow-ups:
- host_env::winapi::create_process: switch the new buffer terminator
  checks from `assert!` to fallible validators returning
  `io::ErrorKind::InvalidInput`, so bad inputs stay recoverable at
  the API boundary.
- host_env::winsound::play_sound: reject `Memory(_)` together with
  `SND_ASYNC` (lifetime-unsafe) and `SND_MEMORY` without a
  `Memory(_)` source. Expand `PlaySoundError` into a variant enum.
- vm::stdlib::_winapi::CreateProcess: route the Win32 path/argv strings
  through `as_wtf8().to_wide_cstring()` like the rest of the Windows
  API surface; `expect_str()` could panic on Python strings containing
  lone surrogates.
