Add serialization-control enum for RPC Options (#27676)

* Add test to verify output when deserializing/reserializing empty fields

* Add test to verify serialization from UiTransactionStatusMeta constructors

* Add OptionSerializer

* Use OptionSerializer for inner_instructions

* Use OptionSerializer for loaded_addresses

* Remove Default variant, use into instead

* Add as_ref implementation

* Use OptionSerializer for log_messages and rewards

* Use OptionSerializer for token_balances

* Use OptionSerializer for return_data

* Use OptionSerializer for compute_units_consumed

(cherry picked from commit 360ca07)
