This to_vec is the clone I was able to avoid, which is the most important part of this PR

Nit: maybe move the logic below on the Guest match arm or use an if let FunctionCallType::Host.

Maybe I missed it, but where was this function called?
If it wasn't used at all, I am curious how the compiler hasn't warned us.

to_vecon the serialized flatbuffer slice. A downside of this is that we expose an implementation detail ("FlatBufferBuilder"), but I think this is acceptable forFunctionCall, and not visible to users anyway.write_guest_function_calltake in aFunctionCallrather than a raw slice.validate_host_function_call_bufferguest_call_*benchmarks shows rougly -6% execution speedup on my local machine, but will depend heavily on the types of function calls and parameters used
