The bindings upstream in Relay has been removed so we don't need these builds anymore. The idea is to revisit an FB integration of Flight but it wouldn't use the Relay specific bindings. It's a bit unclear how it would look but likely more like the OSS version so not worth keeping these around. The `dom-relay` name also included the FB specific Fizz implementation of the streaming config so I renamed that to `dom-fb`. There's no Fizz implementation for Native yet so I just removed `native-relay`. We created a configurable fork for how to encode the output of Flight and the Relay implementation encoded it as JSON objects instead of strings/streams. The new implementation would likely be more stream-like and just encode it directly as string/binary chunks. So I removed those indirections so that this can just be declared inline in ReactFlightServer/Client.
