Flutter plugins: update files to match Flutter SDK 3.29.3 template

According to dev-doc/packaging.md re-ran ./tool/plugin-update.sh.

Skipped file changes for Windows and privacy manifests for iOS and macOS
to speed up testing this.

Added TODOs to remove unused method channel implementations for Linux
and Windows.

This enables user projects to update to Android Gradle Plugin 8.13 which
has stricter checks on the compile SDK of project dependencies, like the
plugins. The androidx.fragment dependency and others added by the
Flutter plugin require at least SDK 34.
