Revert "[Android] Add support for text processing actions (flutter#44579

)" (flutter#46788)

This reverts commit d93fe23.

This change is causing integration tests to fail on attempts to roll the latest master version of flutter into the packages repo.

See a sample failure here: https://logs.chromium.org/logs/flutter/buildbucket/cr-buildbucket/8767521956894285553/+/u/Run_package_tests/native_integration_tests/stdout

The root cause seems to be that we are getting request codes in `onActivityResult` that we never added to the `requestsByCode` map, so the call to remove returns null (and we then call success getting a NPE).

More info: 
1. There is a [discussion in discord here](https://discord.com/channels/608014603317936148/1161718667566919761/1161721935927980052)
2. And the failure can be reproduced by running `dart run script/tool/bin/flutter_plugin_tools.dart native-test --android --packages file_selector` from the root of the packages repo (with a flutter checkout that contains these changes).
