[Windows][Impeller] DXGI shared-handle external textures crash in flutter_windows.dll

Steps to reproduce

Create a Flutter Windows application that renders four Texture widgets.
Register a native Windows GPU surface texture for each widget using:
- flutter::GpuSurfaceTexture
- kFlutterDesktopGpuSurfaceTypeDxgiSharedHandle
In the plugin, create a D3D11 device and two DXGI_FORMAT_B8G8R8A8_UNORM textures per Flutter texture with D3D11_RESOURCE_MISC_SHARED.
Decode four video streams concurrently. For each decoded frame:
- Render it to the current D3D11 texture.
- Call ID3D11DeviceContext::Flush().
- Call TextureRegistrar::MarkTextureFrameAvailable(textureId).
Run the application on Windows with Impeller enabled:
```
flutter run -d windows
```

As soon as the first frames are rendered, the process terminates with an access violation:

[ednet/windows] First frame rendering complete: live=1
[ednet/windows] Unhandled native exception: code=0xc0000005,
module=...\flutter_windows.dll, offset=0x2c55f7
Lost connection to device.

Run the identical application with Impeller disabled:
```
flutter run -d windows --no-enable-impeller
```
Video playback and disposal of all four textures complete without a crash.

Expected results

Windows applications should be able to render and dispose DXGI shared-handle external textures with Impeller enabled without an access violation.

Actual results

With Impeller enabled, Flutter crashes in flutter_windows.dll immediately after the first D3D11 frames are rendered. The same plugin and streams work correctly with --no-enable-impeller.

I fixed a problem with windows external texture in #191017, can you please try to reproduce your problem on main?

I tested the reproduction project against the current main branch, and the crash no longer occurs with Impeller enabled. Thanks for the fix!
