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.

Relands https://github.com/flutter/flutter/pull/150808
The original version of the pr [accidentally deleted the back button](https://github.com/flutter/flutter/pull/150808#discussion_r1655444210), which didn't block the app building but made the test hang because it couldn't back out of the demo pages.
Repro-ed the failure, and then tested that
```
new_gallery_opengles_impeller__transition_perf
new_gallery__transition_perf
new_gallery_impeller_old_zoom__transition_perf
new_gallery__crane_perf
new_gallery_impeller__transition_perf
```
All pass on my pixel 7 pro, with ` dart bin/test_runner.dart test -t <test>`, after re-adding the mistakenly deleted content.
Did not test on an iOS device (I don't have one), but those tests were failing for the same reason from what I can tell:
```
> reply@study
[2024-06-26 12:49:21.884543] [STDOUT] stdout: [ ] scrolling to demo
[2024-06-26 12:49:22.412479] [STDOUT] stdout: [ +527 ms] tapping demo
[2024-06-26 12:49:28.075978] [STDOUT] stderr: [+5663 ms] VMServiceFlutterDriver: tap message is taking a long time to complete...
```
Which is the same error, and which makes sense - they got stuck because they couldn't back out of the page.
Sorry for the churn ð

Reason for reverting: Causing the new_gallery tests to hang.
I can repro now though, so should be able to find a fix shortly

This change reverts the following previous change:
Removes the `dual_screen` package from `new_gallery`. Unblocks the fourth attempt to land https://github.com/flutter/engine/pull/53001.
PR #147801 introduced some convenient `AnimationStatus` getters, but I just realized that `AnimationController` now has 2 getters for the same thing: `isAnimating` and `isRunning`.
The intent of this pull request is to correct that mistake, and implement the getters in the appropriate places.
This PR is step 12 in the journey to solve issue #136139 and make the
entire Flutter repo more readable.
Most of it involves implementing switch expressions, and there's also a
few other random things that I wanted to clean up a bit.
Fixes https://github.com/flutter/flutter/issues/143482
This brings in the gallery more or less as is:
* Removed localizations
* Ensure tests still run (locally verified, will switch CI later).
* Removed deferred components
* Fixup pubspec
