Refactor Flutter Gradle Plugin so it can be applied using the declarative plugins {} block (#123511)
This PR aims to resolve #121552.

Resources used:
- [Developing Plugins](https://docs.gradle.org/current/userguide/custom_plugins.html)
- [Using Gradle Plugins](https://docs.gradle.org/current/userguide/plugins.html#sec:plugins_block)
- [Composite Builds Plugin Development Sample](https://docs.gradle.org/current/samples/sample_composite_builds_plugin_development.html)

This PR also paves way for #121541, because apps will no longer have:

```groovy
apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"
```

hardcoded. Instead, they'll use:

```groovy
plugins {
    // ...
    id "dev.flutter.flutter-gradle-plugin" // the exact name is tentative
}
```

This directory contains templates for flutter create.

The *_shared subdirectories provide files for multiple templates.

  • app_shared for app and skeleton.
  • plugin_shared for (method channel) plugin and plugin_ffi.

For example, there are two app templates: app (the counter app) and skeleton (the more advanced list view/detail view app).

  ┌────────────┐
  │ app_shared │
  └──┬──────┬──┘
     │      │
     │      │
     ▼      ▼
┌─────┐    ┌──────────┐
│ app │    │ skeleton │
└─────┘    └──────────┘

Thanks to app_shared, the templates for app and skeleton can contain only the files that are specific to them alone, and the rest is automatically kept in sync.
