This change reverts the following previous change:
This PR introduces a significant refactoring of the web engine's
rendering layer by unifying the `Surface` and `Rasterizer`
implementations. These components have been moved from being
renderer-specific to a generic `compositing` directory, making the
architecture more modular and easier to maintain. The rasterizers are
now renderer-agnostic and are provided with renderer-specific surface
factories via dependency injection. A new `CanvasProvider` abstraction
has also been introduced to manage the lifecycle of the underlying
canvas elements.

A key outcome of this work is that the Skwasm backend now correctly
handles WebGL context loss events. This was achieved by refactoring
`SkwasmSurface` to allow the Dart side to manage the `OffscreenCanvas`
lifecycle. A communication channel between the main thread and the web
worker is now used to gracefully handle context loss and recovery. This
effort also included fixing several related bugs around surface sizing,
resource cleanup, and callback handling in multi-surface scenarios.

To validate these changes, new testing APIs have been added to allow for
the creation of renderer-agnostic surface tests. A new test file,
`surface_context_lost_test.dart`, has been added to verify the context
loss and recovery behavior across all supported renderers, ensuring the
new architecture is robust and reliable.
