feat: allow any type instead encodable in evaluation series data (#446)

**Requirements**

- [ ] I have added test coverage for new or changed functionality
- [ ] I have followed the repository's [pull request submission
guidelines](../blob/v9/CONTRIBUTING.md#submitting-pull-requests)
- [ X ] I have validated my changes against all supported platform
versions

**Related issues**

Provide links to any issues in this repository or elsewhere relating to
this pull request.

**Describe the solution you've provided**

Requirement for EvaluationSeriesData changed from Encodable to Any since
it doesn't need serialization.

**Describe alternatives you've considered**

No other alternative considered since EvaluationSeriesData is not
serializable.

**Additional context**

Needed by Observability plugin for swift.
