Orchestrator `ResponseDeserializer` codegen and auth (#2494) 

* Convert interceptor fns to macro invocations

Co-authored-by: John DiSanti <jdisanti@amazon.com>

* Add unmodeled error to ServiceError and bring in EventLog

Co-authored-by: John DiSanti <jdisanti@amazon.com>

* Simplify and test `EventLog`

* Attempt to integrate the event log with the orchestrator

* fix: error type in integration test
update: retry handling in orchestrator

* update: set the runtime plugins to do nothing instead of panic when called on

* Introduce a construct for type erasure

* Eliminate several generics and add phased error handling

* Code generate the `ResponseDeserializer` trait impls

* CI fixes

* Reorganize the new runtime crates

* Create the `Identity` type

* Reorganize orchestrator traits and accessors

* Set up code generated test environment for the new runtime

* Add initial auth orchestration implementation

* Fix clippy lint

* Incorporate feedback

* Fix external types lint
