### Issue Link:
What is the link to the issue this cherry-pick is addressing?

#189039

### 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 of production apps (the app crashes on launch).
This information is for domain experts and release engineers to understand the consequences of saying yes or no to the cherry pick.

Release builders should match main. These builders were renamed in #189040 to increase the number of shards. Without this change, the stable release branch will try to run the old builder names and fail because the infra config is missing.

There will be a follow-up cherry-pick to bring it out of bringup when they pass in post-submit #189368

### Changelog Description:

### Issue Link:
What is the link to the issue this cherry-pick is addressing?

#188161

### Impact Description:

This issue can causes crashes in apps that use external textures (often used for rendering video).  On Arm Mali GPUs each frame may leak a file descriptor, and the app will crash when the process reaches the file descriptor limit.

### Changelog Description:

#188161 When apps that use external textures run on some GPUs (such as Arm Mali), it can cause a resource leak that eventually crashes the app.

Are you confident that your fix is well-tested by automated tests?

### Validation Steps:
What are the steps to validate that this fix works?

* Run the example app from the `flutter-webrtc` package on a Mali-based Android device
* Go to the "GetUserMedia" screen and turn on the camera.
* Watch the count of file descriptors in `/proc/[pid]/fd` for the app process and check that it does not increase as the captured video is displayed
