[many] More v1 embedding deletion that was missed in #6494 (#6923)

There were some additional v1 Android embedding references missed by #6494.

This PR aims to remove those missed references.

I built the android example app of each plugin affected here on the [deletion branch](flutter/engine#52022) to be completely sure:

Final testing, I tested that the `all_packages` app builds on the v1 embedding deletion branch: 
```
$ ./.ci/scripts/create_all_packages_app.sh && cd all_packages
...
$ flutter build apk --debug --local-engine-src-path=/Users/mackall/development/engine/src --local-engine=android_debug_arm64 --local-engine-host=host_debug

Running Gradle task 'assembleDebug'...                              4.8s
� Built build/app/outputs/flutter-apk/app-debug.apk
```

� 

Linux repo checks are failing 
```
The following packages had errors:
  packages/google_maps_flutter/google_maps_flutter:
    Missing CHANGELOG change
  packages/palette_generator:
    Missing CHANGELOG change
  packages/quick_actions/quick_actions:
    Missing CHANGELOG change
  packages/webview_flutter/webview_flutter:
    Missing CHANGELOG change
```
The only changes to these packages are `xml` changes to example apps which won't cause build failures even when the v1 embedding is deleted (they will just be unused). So I believe these changes should be version exempt.
