[bug] Could not build with windows7-compat

[liudonghua123]

Describe the bug

I followed the instructions on https://tauri.app/v1/guides/building/windows#supporting-windows-7.

Add "windows7-compat" to tauri dependences in Cargo.toml and configured webviewInstallMode in tauri.config.json.

{
  "tauri": {
    "bundle": {
      "windows": {
        "webviewInstallMode": {
          "type": "embedBootstrapper"
        }
      }
    }
  }
}

Then the build failed with the following errors on linux, windows and macos.

Reproduction

1. Add "windows7-compat" to tauri dependences in Cargo.toml
2. configured webviewInstallMode in tauri.config.json
3. yarn tauri build

Expected behavior

No errors.

I tried to specify once_cell dependence in Cargo.toml and it works for me.
