Improvement: Hash-keyed Try-It-Out parameter value storage (#4670)

* allow param update by identity + hashed value storage

* add specActions.changeParamByIdentity

* add identity-based lookup support in spec selectors

* migrate `changeParam` usage to `changeParamByIdentity`

* migrate usage of `parameterWithMeta` to `parameterWithMetaByIdentity`

* update invocations of `changeParamByIdentity` to match fn signature

* use OrderedMap throughout hash-based selectors for consistency

* normalize usage of ParameterRow `onChange`

* migrate bug 4557 tests to reflect new ParameterRow interface

* remove exclusive test blocks

* linter fixes

* copy Parameters changes into OAS3 wrapper

* use rawParam for meta lookups in ParameterRow
