…utter#181742)

In CanvasKit, `MakeMatrixTransform` returns null if the matrix is
non-invertible (e.g., all zeros or zero scale). Previously, the web
engine assumed this would always return a valid object, leading to a
crash when calling methods like `delete()` or `getOutputBounds()` on the
null result.

This change:
- Updates `MakeMatrixTransform` signature to allow returning null.
- Gracefully handles null filters in `CkMatrixImageFilter` by skipping
the borrow callback.
- Defaults `filterBounds` to `ui.Rect.zero` when the filter is null,
indicating that no content is rendered.
- Adds a comprehensive test suite to ensure non-invertible matrices do
not cause crashes during scene building or painting.

Fixes flutter#181411
