Add 'completed' ScriptPromiseProperty for ImageDecoder API.

This is a non-breaking change which signals when all data has been
received by the ImageDecoder. Clients can wait on the completed
promise to resolve if they so choose.

This also causes errors to close the decoder so we can ensure
reliable resolution of the completed property.
