ci(windows): use DotSlash for zstd in rust-release-windows (#11542)

Browse Source

## Why
Installing `zstd` via Chocolatey in
`.github/workflows/rust-release-windows.yml` has been taking about a
minute on Windows release runs. This adds avoidable latency to each
release job.

Using DotSlash removes that package-manager install step and pins the
exact binary we use for compression.

## What Changed
- Added `.github/workflows/zstd`, a DotSlash wrapper that fetches
`zstd-v1.5.7-win64.zip` with pinned size and digest.
- Updated `.github/workflows/rust-release-windows.yml` to:
  - install DotSlash via `facebook/install-dotslash@v2`
- replace `zstd -T0 -19 ...` with
`${GITHUB_WORKSPACE}/.github/workflows/zstd -T0 -19 ...`
- `windows-aarch64` uses the same win64 upstream zstd artifact because
upstream releases currently publish `win32` and `win64` binaries.

## Verification
- Verified the workflow now resolves the DotSlash file from
`${GITHUB_WORKSPACE}` while the job runs with `working-directory:
codex-rs`.
- Ran VS Code diagnostics on changed files:
  - `.github/workflows/rust-release-windows.yml`
  - `.github/workflows/zstd`
