[pigeon] Reland: Add an initial example app (#3832)
Relands https://github.com/flutter/packages/pull/3761, with the native runners re-created from stable. The important change was the principle class in the macOS Info.plist being NSApplication instead of FlutterApplication, since the latter doesn't exist on stable.
(The pigeon versions also changed because when I re-created the app I re-ran pigeon, and had a slightly newer version.)
[pigeon] Add Swift Package Manager integration to example app (#8225)
This migrates Pigeon's example app to have Swift Package Manager integration. This raises the example apps' Flutter SDK requirement to 3.24.0 or higher.
This also checks-in CocoaPods integration stuff that was missing.
I will get a text exemption for this change.
The example apps were migrated using the following commands:
```
dart run script/tool/bin/flutter_plugin_tools.dart build-examples --ios --swift-package-manager
dart run script/tool/bin/flutter_plugin_tools.dart build-examples --macos --swift-package-manager
```

[various] Migrate example apps' AppDelegate.swift (#8155)
Migrated by running:
```
dart run script/tool/bin/flutter_plugin_tools.dart build-examples --ios --swift-package-manager
dart run script/tool/bin/flutter_plugin_tools.dart build-examples --macos --swift-package-manager
```
Tests aren't updated as this change should not affect semantics. I will get a test exemption.

Remove use_modular_headers! from Podfiles (#7796)
â ï¸ _This PR does not update packages' versions as it only affects unpublished parts of example apps and tests._
We added use_modular_headers! to our Podfiles as we originally planned to phase out use_frameworks! (see https://github.com/flutter/flutter/pull/42204). However, our plans have now changed and we are instead phasing out CocoaPods entirely in favor of Swift Package Manager.
CocoaPods's use_frameworks! and use_modular_headers! are two different overlapping options that should not be used together. This change removes the use_modular_headers! from example apps' Podfiles. This change does not affect packages themselves.
