Disable CocoaPods input and output paths in Xcode build phase and adopt new Xcode build system (#34167)

Updates the Podfile template to use the CocoaPod disable_input_output_paths installation option which prevents the [CP] Embed Pods Frameworks build phase from outputting the Flutter.framework files.

* Add dartdoc generation README helper images

* Add test doc generation workflow section

* Add info about interpolating into templates

* Gradle generates ELF shared libraries instead of AOT snapshots.
* `flutter build apk/appbundle` supports multiple `--target-platform` and defaults to `android-arm` and `android-arm64`.
* `flutter build apk` now has a flag called `--split-per-abi`.

This is a small follow up to the previous AndroidX PR: https://github.com/flutter/flutter/pull/31028

This fixes an issue mentioned [here](https://github.com/flutter/flutter/issues/28805) where the androidX flag for a module is not set when creating a new project:

`flutter create --androidx -t module my_flutter`

Adds two new custom analytics dimensions: run_target_os_version and run_target_mode_name that are sent with each invocation of flutter run and show up in Google Analytics as "screens".
