Remove Windows sandbox resource stamping (#23764)

## Why

The `codex-windows-sandbox` crate was embedding Windows resource
metadata through a package-level `build.rs`. Because that package also
exposes the `codex_windows_sandbox` library, downstream binaries that
link the library could inherit `FileDescription` / `ProductName` values
of `codex-windows-sandbox`.

That made ordinary Codex binaries, including the long-lived `codex.exe`
app-server sidecar, appear as `codex-windows-sandbox` in Windows UI
surfaces such as Task Manager / file properties.

We do not rely on this metadata enough to justify a larger bin-only
resource split, so this removes the resource stamping entirely.

## What changed

- Removed the `windows-sandbox-rs` build script that invoked `winres`.
- Removed the setup manifest that was only consumed by that build
script.
- Removed the `winres` build dependency and corresponding `Cargo.lock` /
`MODULE.bazel.lock` entries.
- Removed the now-unused Bazel build-script data.

## Verification

- `cargo build -p codex-windows-sandbox --bins`
- `cargo build -p codex-cli --bin codex`
- `bazel mod deps --lockfile_mode=update` via Bazelisk, with local
remote-cache-disabling flags because `bazel` is not installed on PATH
here
- `bazel mod deps --lockfile_mode=error` via Bazelisk, with the same
local flags
- Verified rebuilt `codex.exe`, `codex-command-runner.exe`, and
`codex-windows-sandbox-setup.exe` now have blank `FileDescription` /
`ProductName` fields.
- `cargo test -p codex-windows-sandbox` still fails on two legacy
Windows sandbox tests with `CreateRestrictedToken failed: 87` and the
follow-on poisoned test lock; 85 passed, 2 ignored.
