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
Reverts: flutter/flutter#150808

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.
Removes these two discontinued plugins from `dev/integration_tests/flutter_gallery`
[`device_info`](https://pub.dev/packages/device_info):
Apparently the video playback doesn't work on iOS simulators (I wasn't able to verify this, as I don't have an iOS simulator installed). I removed the guard against running on those simulators, and replaced with a note in the README.
[`connectivity`](https://pub.dev/packages/connectivity):
This plugin was used to play the bee video from the network. I changed the demo so that the bee video is instead also played from an asset (like its friend the butterfly), and then removed the use of the plugin.
Unblocks the re-land of https://github.com/flutter/engine/pull/53462 (itself a reland ð), because of https://github.com/flutter/flutter/pull/150465#issuecomment-2181403712.

Entire PR is just the output of

DDS was temporarily pinned to 4.1.0 because 4.2.0 triggered some test
failures (see https://github.com/flutter/flutter/pull/147250). Those
failures should be fixed by vm_service 14.2.2, so this unpins DDS and
rolls both of these packages (along with devtools_shared, which is a DDS
dependency).
(If the bot updates vm_service before this is done, I can rebase over
that will reduce the size of this PR to just a few files)
## Description
This introduces a list of packages that we will explicitly not pin. It is to be used for things where the package isn't actually published, but is a transitive dependency of another package included in the SDK. This happens with the `macros` package, for instance, which depends on the private, unpublished, `_macros` package where the SDK does some tricky things to depend on it (it depends on "any", but ships it as part of the SDK).
Also ran `flutter update-packages --force-update` to update all of the pubspec files.
## Related Issues
- Fixes#147656
## Tests
- Added a test that makes sure that explicitly unpinned packages don't show up in the pinned list.
The interface for `ArgResults` from `package:args` has added new fields. Change the implementations of these in the conductor to extend `Fake` so that these aren't analyzer errors.
This broke the pub roll here: https://github.com/flutter/flutter/pull/146642#issuecomment-2050169629
This PR is to update material_color_utilities package version to the latest. `material_color_utilities/scheme/scheme_fruit_salad.dart` and `material_color_utilities/scheme/scheme_rainbow.dart` are exported after version 0.9.0.
Once this PR is merged, we don't need to explicitly import these two files like the change in PR #144805, which breaks some dependencies in `Google testing`.
