Fixes a "Null check operator used on a null value" crash when a scroll view contains a `LayoutBuilder`.
### Impact Description:
What is the impact (ex. visual jank on Samsung phones, app crash, cannot ship an iOS app)? Does it impact development (ex. flutter doctor crashes when Android Studio is installed), or the shipping production app (the app crashes on launch)
The app may crash if there a `LayoutBuilder` child inside of a `RenderSliverMultiBoxAdaptor` (which `SliverList` uses), and that child suddenly becomes offstage and kept-alive.
One example is when you have a TextField inside of a LayoutBuilder which is part of a `SliverList`. The app crashes ("Null check operator used on a null value") even in release mode when the user drags so that the text field becomes offscreen. All 3 are popular widgets so I think this combination will not be that uncommon.
### Workaround:
Is there a workaround for this issue?
There's no known workaround for this issue. You can increase the cache extent to prevent the child from becoming kept-alive but this is not really feasible for long / infinite list as it will go OOM fast.
### Risk:
What is the risk level of this cherry-pick?
This should be a relatively safe fix.
Despite changing an important flag in RenderObject from `RenderObject?` to `bool?`, there's only one change in behavior:
in `RenderObject.dropChild`: https://github.com/flutter/flutter/pull/169958/files#diff-4c298197a8aa7831a26eece096c8b8b07773ba1f5376d848ea4ef2924b606e9fL2052
which originally set the flag to `null` for the entire subtree until a new relayout boundary is reached, now it only sets the flag to `null` for the root of the subtree.
In release mode, the only place the framework cares about whether the flag is null is [here](https://github.com/flutter/flutter/pull/169958/files#diff-4c298197a8aa7831a26eece096c8b8b07773ba1f5376d848ea4ef2924b606e9fR2342) (everywhere else `null` just means `false`), and that won't actually introduce any correctness issues because if the node originally enters the `if` block in line 2343 it will still enter the `if` block after the patch.
Also, the fix was merged a couple weeks ago and I haven't seen bug reports associated with the fix yet.
### Test Coverage:

### Changelog Description:
Fix Flutter Windows on devices that only support OpenGL ES 2, like computers with Intel graphics cards.
### Impact Description:
Flutter Windows 3.29.0 and higher crashed immediately on startup on computers using Intel HD Graphics graphics cards.
### Workaround:
None, other than downgrading your Flutter SDK to 3.27.4 or lower.
### Risk:
What is the risk level of this cherry-pick?
### Test Coverage:
Are you confident that your fix is well-tested by automated tests?
### Validation Steps:
This bug does not reproduce on Flutter's infrastructure. The fix was manually tested on several Windows devices, including affected devices that use Intel HD Graphics graphics cards.
Impacted Users: iOS and macOS Flutter developers
Impact Description: iOS/macOS workflows may not behave as expected due to missing dev dependencies.
Workaround: Yes, run in debug mode, such as `flutter build ios --debug --config-only`
Risk: low
Test Coverage: yes
Validation Steps: Run `flutter build ios` on a project with dev dependencies and should see them in the GeneratedPluginRegistrant

### Impact Description:
What is the impact (ex. visual jank on Samsung phones, app crash, cannot ship an iOS app)? Does it impact development (ex. flutter doctor crashes when Android Studio is installed), or the shipping production app (the app crashes on launch)
The memory usage of apps using Impeller/Vulkan will increase as frames are rendered. Memory consumption will grow until the Android activity enters the stopped state.
### Workaround:

This fix is a revert to a PR which landed in the current stable.
Updates `engine.version` for 3.32.2 stable hotfix release to the last cherry-pick SHA: d88a6751a8
I think this is required because there were engine changes in a previous cherry-pick (https://github.com/flutter/flutter/pull/169772) not included in the 3.32.1 stable hotfix release.

### Issue Link:
What is the link to the issue this cherry-pick is addressing?
https://github.com/flutter/flutter/issues/163591
### Changelog Description:
Normalizes file paths in every depfile, especially on Windows. It eliminates the inconsistency that can occur when other codes find the file paths are different and produce unexpected results.
### Impact Description:
The most noticeable impact so far is that people are unable to build flavored Android packages on Windows repeatedly until the next clean.
### Workaround:
Is there a workaround for this issue?
The workaround is to manually patch the project's gradle script: https://github.com/flutter/flutter/issues/163591#issuecomment-2887039609
From my experience, the patch is not always working and is hard to maintain.

Fixes https://github.com/flutter/flutter/issues/156793
### Issue Link:
https://github.com/flutter/flutter/issues/156793
### Changelog Description:
Fix flaky crash when targeting web applications via IDEs using the DAP.
### Impact Description:
The `flutter debug-adapter` process started by IDEs can crash when requesting isolate information from a Flutter web application that has disposed its isolate (i.e., at shutdown or due to a hot restart).
This is the top crasher for `flutter_tools`, accounting for ~66% of all crashes for 3.32.0.
### Workaround:
Is there a workaround for this issue?
No.
### Risk:
This CP is low risk as only additional exception handling was added to the DAP logic in `package:dds` (see https://dart-review.googlesource.com/c/sdk/+/431060) to handle the specific case outlined in the issue.
### Test Coverage:
This issue is difficult to reproduce without injecting test-only code via custom VM service RPCs across multiple repositories. Testing was done manually with this approach, but the testing code is not committed.
### Validation Steps:
IDE extensions don't crash when interacting with Flutter Web applications during hot restart / application shutdown.

pixel diffing is difficult to do without being flakey, video rendering pixel diffing is even harder. Was tested manually in the initial pr.
### Validation Steps:
What are the steps to validate that this fix works?
Using a device that utilizes Vulkan rendering, start the video_player example app, press play on the video, then scroll up or down - the visual flickering should be evident.
This reverts commit aed4bfd318f189d648e595b89442fc19e3147b47.
`flutter_packaging` builders only should run on `stable` or `beta`, the original definition was correct.

### CP request for https://github.com/flutter/flutter/pull/167677 into flutter-3.32-candidate.0
**Impacted Users:** Some subset of widget inspector users with a specific configuration of `package:go_router`, see upvotes and comments on https://github.com/flutter/flutter/issues/166118.
**Impact Description:** Depending on how users have configured their routes using `package:go_router`, enabling / disabling the widget inspector can be destructive to their app's routing state, preventing them from inspecting widgets on secondary screens of their app.
**Workaround:** No workaround available.
**Risk:** Low
**Test Coverage:** Yes, tests were added and this has been manually tested as well
**Validation Steps:**
- Run a Flutter app
- Open the DevTools Inspector for the running app
- Toggle "Select widget mode"
- An additional button has been added to the on-device inspector that allows developers to both interact with their app (e.g. navigate to a new page) and select widgets while in Widget Selection mode. See gif below.
