This change was dropped out of #26227 because it seems to inexplicably result in timeouts talking to the VM service on Windows Cirrus. After 1 month of periodically debugging it, it just started passing 🤷‍♂️.

In Dart 2, it is a compile-time error if a superinitializer
appears in an initializer list at any other position than at the end so this
rule is made redundant by the Dart analyzer's basic checks and is no longer
necessary.

This adds support for logical and physical key information inside of RawKeyEvent. This allows developers to differentiate keys in a platform-agnostic way. They are able to tell the physical location of a key (PhysicalKeyboardKey) and a logical meaning of the key (LogicalKeyboardKey), as well as get notified of the character generated by the keypress. All of which is useful for handling keyboard shortcuts.

This PR builds on the previous PR (#27620) which generated the key code mappings and definitions.

Now the sample analyzer can be run locally with:

dart dev/bots/analyze-sample-code.dart --temp=/tmp/samples

And it leaves /tmp/samples around so you can take a look at the code that was generated to see if it's the artificial environment that the samples are evaluated in that is the culprit for a failed analysis.

Before, you had to specify the whole path to the dart executable, and had to modify the code to keep the tempdir around.

Try to detect Gradle error messages that hint at AndroidX problems, and
warn in the logs about the potential problem and point to documentation
on how to fix the issue.

Unfortunately the Gradle errors based on this root issue are varied and
project dependent. It's probably better to still leave the message
intact in case the problem is unrelated.

Also filters out the plugin warning message pending in
flutter/plugins#1138. It's still valuable to add that for people on
previous versions of Flutter, but this link should override that message
for anyone on an up to date version of Flutter.

This adds a keycode generator that incorporates input from the Chromium and Android source trees, as well as some local tables, to generate static constants for the LogicalKeyboardKey and PhysicalKeyboardKey classes, as well as mappings from each of the platforms we support so far (currently only Android and Fuchsia).

This code generator parses the input files, generates an intermediate data structure (`key_data.json`) that is checked in, and then generates the Dart sources for these classes and some static maps that will also be checked in (but are not included in this PR).

The idea is that these codes don't change often, and so we don't need to generate them on every build, but we would like to be able to update them easily in the future if new data becomes available. If the existing data disappears or becomes unusable, we can maintain the checked-in data structure by hand if necessary, and still be able to generate the code.

This PR only contains the code generator, not the classes themselves. In another follow-on PR, I'll run the generator and check in the output of the generator.

These changes are **backwards incompatible**. Tests that verify OutlineButton visuals, for example golden image tests, will need to be updated.

For `fuchsia_compat.dart` Instead of using `runSync`, use `run` to avoid
deadlock when attempting to access specific resources like the Hub in Fuchsia.

The specific example is that in Fuchsia, the `find` command is
attempting to explore `out` which hasn't yet been serviced, as `find` is
blocking on it, causing a deadlock.

Before this, we had several places where an isReleaseMode was defined, all with the same definition. This just makes it more broadly visible to allow our users to use it, as well as creating debug and profile versions, and adding a device lab test for it.

Since this is a const value, this makes it possible for a developer to easily mark blocks that can be removed at AOT compile time.
