This change reverts the following previous change:
Reland after #169357.
Switch Flutter to use pub workspaces as a preparation to unpin selected
packages.
Assumptions:
1. No packages in this repository are published to pub.dev --> We can
use `any` dependencies in most local pubspecs, as the global constraint
defines the version. An exception are the packages used outside of this
repo with an `sdk` dependency, namely `flutter_localizations`,
`flutter_test`, and `flutter`.
2. The "universes" `{flutter_tools}` and `{flutter,
flutter_localizations, flutter_goldens}` can use different packages
versions, as they are not resolved together. --> We do not need to
upgrade them in sync, we can first do one "universe", then the other.
Based on these assumptions, we use
https://github.com/mosuem/pubspec_merger.dart to merge all packages in
the `flutter` universe into a top-level pub workspace.
The `flutter` and `flutter_tools` workspaces being separate also ensures
that changes to `flutter` will not inadvertently break `flutter_tools`,
with not-so-nice consequences for our users which would be unable to run
`flutter upgrade`.
There is a third "top-level" pubspec besides `./pubspec.yaml` and
`packages/flutter_tools/pubspec.yaml`, namely
`packages/flutter_tools/.../widget_preview_scaffold/pubspec.yaml`. This
is an artifact due to it living under `flutter_tools`, so it can't be
part of the `./pubspec.yaml` workspace. Moving it would be a larger
change, and out of the scope of this PR.
This required a rewrite of the update-packages tool, but the main
functionality stays the same, as well as the argument names, to ensure a
seamless transition.

Powered by the new and amazing `unnecessary_ignore` lint.
We're not enabling this lint by default because being able to
temporarily use ignores that don't ignore anything is a powerful tool to
enable migrations. We should turn this lint on locally periodically,
though, and clean up all outdated ignores.
This auto-formats all *.dart files in the repository outside of the
`engine` subdirectory and enforces that these files stay formatted with
a presubmit check.
**Reviewers:** Please carefully review all the commits except for the
one titled "formatted". The "formatted" commit was auto-generated by
running `dev/tools/format.sh -a -f`. The other commits were hand-crafted
to prepare the repo for the formatting change. I recommend reviewing the
commits one-by-one via the "Commits" tab and avoiding Github's "Files
changed" tab as it will likely slow down your browser because of the
size of this PR.

This change reverts the following previous change:
In preparation for changing engine builds to be unstripped by default
https://github.com/flutter/engine/pull/52852, which will allow us to
make progress towards resolving
https://github.com/flutter/flutter/issues/60240.
Tricks AGP in to downloading the NDK when building a flutter app (that
uses the FGP, which to my knowledge is all ways of building flutter
apk/aab/aar).
I want to follow this up by modifying the tool to search for the log
line that the NDK is missing (making it throw an error in that case) as
a safeguard, because that would be the last line of defense before we
accidentally build a bloated app. The safeguard won't work for add to
app, from what I understand, because while they use the FGP (so they
should be forced to be download the NDK) they don't invoke the flutter
tool, and therefore won't invoke the custom error handling of
[`gradle_errors.dart`](https://github.com/flutter/flutter/blob/master/packages/flutter_tools/lib/src/android/gradle_errors.dart)
Some details
1. Respects existing values for `externalNativeBuild.cmake.path` for
apps that actually use it.
2. Silences some warnings that would otherwise appear for add to app
builds or builds that manually invoke gradle:
```
C/C++: CMake Warning (dev) in CMakeLists.txt:
C/C++: No project() command is present. The top-level CMakeLists.txt file must
C/C++: contain a literal, direct call to the project() command. Add a line of
C/C++: code such as
C/C++: project(ProjectName)
C/C++: near the top of the file, but after cmake_minimum_required().
C/C++: CMake is pretending there is a "project(Project)" command on the first
C/C++: line.
C/C++: This warning is for project developers. Use -Wno-dev to suppress it.
C/C++: CMake Warning:
C/C++: Manually-specified variables were not used by the project:
C/C++: CMAKE_EXPORT_COMPILE_COMMANDS
C/C++: CMAKE_LIBRARY_OUTPUT_DIRECTORY
C/C++: CMAKE_RUNTIME_OUTPUT_DIRECTORY
```
3. Our ci installs the NDK at an abnormal place that AGP can't find
without help. I've modified all the `build.gradle`s that we have checked
in to point to the pre-installed path. **But some of our tests make a
new app from the templates, and those tests will now start downloading
the NDK** (as they won't be able to find it at it's current path from
templates). We could resolve this by actually fixing
https://github.com/flutter/flutter/issues/136666. This would be a very
significant lift from what I understand - we rely on this hardcoding in
a lot of places in our infra.

This change reverts the following previous change:
I recently noticed the following log when building an app in verbose mode:
```
This Android Gradle plugin (8.1.0) was tested up to compileSdk = 33 (and compileSdkPreview = "UpsideDownCakePrivacySandbox").
You are strongly encouraged to update your project to use a newer
Android Gradle plugin that has been tested with compileSdk = 35.
```
It looks like AGP would like us to use a newer AGP version if we want to use compileSdk 35 (which we do). This pr upgrades the tests, in advance of updating the templates.

Rework on the text button use case to pass [b/347102786](https://b.corp.google.com/347102786),
After talking with the tester, it seems like there isn't an issue with the A11y of the text button, rather just how the test case is set up. In order for the text case to pass, there needs to be real time feedback of an action that is done by pressing the text button (think of a dialog popup, or form submission notification).
So I rewrote the test case to mimic a simple form with a submit button that once submitted, will let the user know it is submitted with a snack bar notification. https://screencast.googleplex.com/cast/NTM0ODc1NDIxMDE2MDY0MHwzYWI4MTZhMS1hMA

Adds Semantic Widget to wrap the contents of each page's AppBar title attribute and adds header: true and headingLevel: 1 as Semantic attributes so the content of the title is compiled as an h1 tag to meet accessibility guidelines that each page must have a h1 tag present. Also updates the test cases for the home page and each use case page to check for its respective h1.
