  -----------
  [orc-rt] Add return serialization to AllocActionFunction::handle. (#205271)

Add a Serializer template parameter to AllocActionFunction::handle and
apply it to the handler's return value before forwarding as the action
result. This lets handler authors return types other than
WrapperFunctionBuffer.

For SPS, AllocActionSPSSerializer is the default Serializer used by
SPSAllocActionFunction::handle. It accepts either:
- WrapperFunctionBuffer (identity pass-through, the existing behavior),
or
- Error (success → empty WFB; failure → out-of-band-error WFB carrying
toString(Err)).

Adds AllocActionTest coverage for both Error-return paths.
