When a context loss occurs on DrawTargetWebgl, this may result in a fallback TextureData
being created. Each of these are currently managed by two different RemoteTextureOwnerClients.
This is not really safe at all.
To fix this, CopyToSwapChain is modified so that it can be supplied a RemoteTextureOwnerClient.
Then CanvasTranslator can inject its own RemoteTextureOwnerClient into CopyToSwapChain, rather
than letting CopyToSwapChain use its own separate internal RemoteTextureOwnerClient.
This also tries to address a few other data consistency bugs with the fallback TextureData.
