This reverts commit 5257f029.

* Building shared C source code as part of the native build for platforms Android, iOS, Linux desktop, MacOS desktop, and Windows desktop.
* Sample code doing a synchronous FFI call.
* Sample code doing a long running synchronous FFI call on a helper isolate.
* Use of `package:ffigen` to generate the bindings.

Remove flutter create --with-driver-test . Fixes #64095

remove intellij references to the v1 embedding jars now that the v2 embeddings are referenced via maven (#55353)

Add `.flutter-plugins-dependencies` to the project, which contains the app's plugin dependency graph (#45379)

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`

* Updating dart.dev related links

* Update packages/flutter_tools/lib/src/base/context.dart

Currently, in pubspec.yaml, semver.org is referred to for more about versioning.
However, the versionCode/versionName could differ on different platforms (iOS, Android, Dart).

This adds more clear and complete information that could help users to understand it better.

See: #27251

* Document module pubspec

* update doc on plugin template

* clarify language

* update the docs for the module template

* update text

Removes some `new`s and other minor cleanup.

We decided that redefining the default for templates was premature. We're going to go back to having "module" in experimental land again, and we'll try again when we have the feature set fully baked.

This keeps the writing of the .metadata files, and writing the template type to them, because that was a good improvement, and there are still a bunch of added tests that improve our coverage.

This renames the "module" template to the "application" template, and makes "application" the default. The existing "app" template is now deprecated.

flutter create also now recognizes the type of project in an existing directory, and is able to recreate it without having the template type explicitly specified (although you can still do that). It does this now by first looking in the .metadata file for the new project_type field, and if it doesn't find that, then it looks at the directory structure. Also, the .metadata file is now overwritten even on an existing directory so that 1) the project_type can be added to legacy projects, and 2) the version of Flutter that updated the project last is updated.

I also cleaned up a bunch of things in create_test.dart, added many more tests, and added an example test to the test/ directory in the generated output of the application template.
