[many] More v1 embedding deletion that was missed in https://github.com/flutter/packages/pull/6494

[gmackall]

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 to be completely sure:

• video_player
• google_sign_in (builds, but only with the fixes to espresso applied).
• espresso
• in_app_purchase
• image_picker (builds, but only with the fixes to both espresso and video_player applied)

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.

cc @stuartmorgan for a versioning question (no rush) - In a PR like this, where a fix to google_sign_in depends on a fix to espresso, will I need to land the fix to the latter first, and then put up a follow up PR to fix the former?

[stuartmorgan-g]

I believe this means it should be safe to land in the same PR

Agreed, I don't expect any issue given that. And if it weren't safe, I would expect presubmits to fail, since the native tests in CI are not using path-based deps.

[stuartmorgan-g]

LGTM modulo making format happy.

Overriding CHANGELOG check: the manifest XML changes are not interesting to clients, so don't need to be mentioned.
