[fidl][go] Handling of nil payloads

With the migration to the new Go bindings, we will stop emitting request
and responses if they have no arguments: this was mistakenly handled as
'messages with size 0' by the encoding, despite the fact that no FIDL
message can have a 0 size.

Instead, the correct approach is to conditionally invoke
encoding/decoding depending on whether a payload should be written.
