This pull request aims to improve code readability, based on feedback gathered in a recent design doc.

There are two factors that hugely impact how easy it is to understand a piece of code: **verbosity** and **complexity**.
Reducing **verbosity** is important, because boilerplate makes a project more difficult to navigate. It also has a tendency to make one's eyes gloss over, and subtle typos/bugs become more likely to slip through.
Reducing **complexity** makes the code more accessible to more people. This is especially important for open-source projects like Flutter, where the code is read by those who make contributions, as well as others who read through source code as they debug their own projects.
<hr>

The following examples show how pattern-matching might affect these two factors:
<details> <summary><h3>Example 1 (GOOD)</h3> [click to expand]</summary>
```dart
if (ancestor case InheritedElement(:final InheritedTheme widget)) {
themes.add(widget);
}
```
Without using patterns, this might expand to
```dart
if (ancestor is InheritedElement) {
final InheritedWidget widget = ancestor.widget;
if (widget is InheritedTheme) {
themes.add(widget);
}
}
```
Had `ancestor` been a non-local variable, it would need to be "converted" as well:
```dart
final Element ancestor = this.ancestor;
if (ancestor is InheritedElement) {
final InheritedWidget inheritedWidget = ancestor.widget;
if (widget is InheritedTheme) {
themes.add(theme);
}
}
```
</details>
<details> <summary><h3>Example 2 (BAD) </h3> [click to expand]</summary>
```dart
if (widget case PreferredSizeWidget(preferredSize: Size(:final double height))) {
return height;
}
```
Assuming `widget` is a non-local variable, this would expand to:
```dart
final Widget widget = this.widget;
if (widget is PreferredSizeWidget) {
return widget.preferredSize.height;
}
```
<br>
</details>
In both of the examples above, an `if-case` statement simultaneously verifies that an object meets the specified criteria and performs a variable assignment accordingly.
But there are some differences: Example 2 uses a more deeply-nested pattern than Example 1 but makes fewer useful checks.
**Example 1:**
- checks that `ancestor` is an `InheritedElement`
- checks that the inherited element's `widget` is an `InheritedTheme`
**Example 2:**
- checks that `widget` is a `PreferredSizeWidget`
(every `PreferredSizeWidget` has a `size` field, and every `Size` has a `height` field)
<br>
<hr>
I feel hesitant to try presenting a set of cut-and-dry rules as to which scenarios should/shouldn't use pattern-matching, since there are an abundance of different types of patterns, and an abundance of different places where they might be used.
But hopefully the conversations we've had recently will help us converge toward a common intuition of how pattern-matching can best be utilized for improved readability.

This updates the codesigning test to account for iOS and macOS binaries in the artifact cache that are _expected_ to not be codesigned.
In https://github.com/flutter/engine/pull/54414 we started bundling dSYM (debugging symbols) within Flutter.xcframework, a requirement for App Store verification using Xcode 16.
We did the same for macOS in https://github.com/flutter/engine/pull/54696.
Unlike the framework dylib, dSYM contents are not directly codesigned (though the xcframework containing them is).

This was partially fixed in flutter/flutter#153787, which added just the extension-safe simulator dSYM, but we also bundle:
* arm64 release dSYM
* arm64 release extension-safe dSYM
* arm64_x86_64 simulator dSYM
In a followup engine patch, we'll stop bundling both the regular and extension-safe simulator dSYMs, but this gets the test passing at tip-of-tree.

The test is checking:
- if all crucial Widgets are initially visible
- if IconButton click will expand existing SliverList
- if IconButton click and mouse scroll will reveal additional SliverList
A pending change to the flutter_drone LUCI recipe is using a logging library that sets the FLUTTER_TEST_OUTPUTS_DIR environment variable (see https://flutter.googlesource.com/recipes/+/b111cd3ef2297e66905cc48c2cfedce0cf1ba46f)
flutter_driver uses FLUTTER_TEST_OUTPUTS_DIR as its output directory if it is set. run_web_tests invokes flutter_driver and needs to look for outputs in that directory.
Not so long ago I remember a very informal conversation that went something like this:
> @matanlurey: I wish I could pass `--dev` or something to `flutter` to run from source.
>
> @christopherfujino: I get what you want, but I don't want to overload the tool with more dev-only things. I would consider a script like `flutter-dev` that does that thing, though.

> @matanlurey: Cool, I might send a PR!
So uh, here it is 6-9 months later. Suggestions welcome.

When attempting to release the Flutter 3.24.1 hotfix, Flutter framework post submits failed due to the following error:
```

```
I've updated the tests to include the listed artifact.
### Open questions
1. Is it possible that the test failed only on the first binary?
2. Do we expect a need to add the remainder of the [entitlement changes](c9b9d5780d)?
3. I am under the assumption that the bots pull from master and are not branch specific, is this a correct assumption?

Move `scroll_direction.0_test.dart` & `growth_direction.0_test.dart` to same directory structure as the example files.
Tests were already present, only had to move them & remove the entries from the missing tests.

Closes https://github.com/flutter/flutter/issues/152325.
This PR is large due to generate `flutter create --platforms android`. A quick summary:
- Moves the integration test from `packages/flutter_driver/test` to `dev/integration_tests`
- Created a sample Flutter app that draws a blue rectangle
- Forked a subset of `package:flutter_goldens` that will work on the standalone Dart VM
- Forked a subset of `goldens.dart` (from `flutter_test`) to `src/native/goldens.dart` (i.e. `matchesGoldenFile`)
This ... works locally, but as usual I have no idea if it will work on Skia Gold so let's roll some dice.
