Attachment: Use a content texture client for Canvas2D

This makes us use a Content texture client for Canvas2D. This is optimal since we use LockSurface to draw the canvas anyway. This will make us use a TextureClientD3D11 and avoid the readback when copying.

This prevents this from hitting a slow path in the Cairo D2D backend.

Could you file a bug, this isn't an acute problem since it's a custom pref, but I'd like to fix it soon! :)
