Adds optional _meta field to Tool (#339)

Browse source 
<!-- Provide a brief summary of your changes -->

## Motivation and Context
The recently released openAI [Apps SDK
](https://developers.openai.com/apps-sdk/reference/#_meta-fields-the-client-provides)adds
a '__meta_' field on the Tool Descriptor. This would be in addition to
it being available on Messages. It remains optional and defaults to an
empty json object, following existing conventions.

Unit tests for serialization added
