Evan Mattson 5f49880d52 Python: Json schema improvements for Union and Optional (#7367) ...

### Motivation and Context

We have some gaps in how we build the JSON schema for function calling
related to Union and Optional types. There is also some work to do
related to handling `Optional` versus `param | None = None`.
