Revert "Make tests more resilient to Skia gold failures and refactor flutter_goldens for extensive technical debt removal (#140101)" (#141814)

That PR somehow made non-matching gold tests not fail at HEAD.

`swift-format` alphabetizes imports.  Alphabetize them in swift template files and integration tests.

I found this as part of https://github.com/flutter/flutter/issues/41129 running `swift-import` on packages.

We pinned to web_socket_channel v2.4.1 because v2.4.2 was retracted, however v2.4.3 is now available.

Change the following in the `flutter create` templates.  I didn't make any auto-migrations for existing apps because none seem that critical:
1. Turn on `ASSETCATALOG_COMPILER_GENERATE_SWIFT_ASSET_SYMBOL_EXTENSIONS` in iOS and macOS.
1. Turn on `BuildIndependentTargetsInParallel` in macOS template.  https://github.com/flutter/flutter/pull/125827/files#r1181817619 
1. Turn on `DEAD_CODE_STRIPPING` in macOS template. 
1. Set `ENABLE_USER_SCRIPT_SANDBOXING=NO` in iOS and macOS template.  `flutter` scripts don't work with this on.  This might require a migration in the future to explicitly turn this one off. However at least for now if the setting isn't present it defaults to `NO`.

Add migration for `LastUpgradeVersion` so users won't see these validation issues in Xcode.

Run migrator on all the example apps.  A few aren't Flutter apps so I edited them in Xcode.

1. Change templates to `IPHONEOS_DEPLOYMENT_TARGET`, `MinimumOSVersion`, and Podfile `platform :ios` to 12.0.
2. Add migrator for Podfile part to migrate `platform :ios, '11.0'` -> `platform :ios, '12.0'`
3. Compile with `-miphoneos-version-min=12.0`
4. Run the migrator on all example apps and integration tests.

1. Move leak_tracker and leak_tracker_testing out of direct dependencies.
2. Move leak_tracker_flutter_testing from dev to prod dependencies for flutter_test

It is prerequisite for https://github.com/flutter/flutter/issues/135856

Pinning the package:web dependency constrains downstream packages from
using newer versions and making sure they support the version pinned in
Flutter. Since the usage of package:web in Flutter is light, we should
instead have a small shim like the engine and keep package:web as a dev
dependency only.

test-exempt: rolling dependencies

Upgrades agp versions and lockfiles for `dev/`. Also changes the lockfile generation script to represent the newer form of the `settings.gradle` template, and therefore also propagates these changes.

~~Potentially related to https://github.com/flutter/flutter/issues/134419~~, but worth doing anyways. (not actually related)

I previously made a PR (#136140) that used `switch` expressions to make some parts of the Flutter codebase easier to understand. It was assigned to the framework team, and @christopherfujino let me know that it was too large to effectively review and recommended breaking it up into smaller pull requests.

Here's a PR that only targets files in the `dev/` directory. Hopefully this will be easier to work with!

(solves issue https://github.com/flutter/flutter/issues/136139)

This version is needed so that dart:js_interop can move to extension
types. Also adds some code to handle some breaking changes:

- Body -> Response. Body was an IDL interface mixin type we exposed in
dart:html. Going forward, users should either use Request or Response.
- Casts to JSAny. These are temporary until we move package:web types to
extension types. Currently, package:web types can't implement JSObject
as JSObject will move to be an extension type itself.

Analyzer's dependency on autosnapshotting causes issues.

Because every version of integration_test from sdk depends on leak_tracker from hosted and autosnapshotting depends on leak_tracker from path, integration_test from sdk is forbidden.
So, because autosnapshotting depends on integration_test from sdk, version solving failed.

This PR also adds transitive dependency on  web_socket_channel, crypto, typed_data. `web_socket_channel` is needed to request retaining path for not GCed objects from VM Service. Two others are needed to serve web_socket_channel.

I'm seeing these in the bot reports every week. Hopefully this is all of
them, and hopefully 4GB is enough.

New feature in upcoming Dart 3.2. See https://github.com/dart-lang/language/issues/2020. Feature is enabled by bumping the min SDK version to 3.2.
