Streaming/SSE

[lmazuel]

TypeSpec needs to support streaming. In particular, there needs to be a way to:

• Declare that an operation takes and returns a conceptual stream
• A way to layer configuration of particular protocols on top, such as SSE
• Built-in support for common streaming protocols, e.g. JSONL and SSE
• Codegen support
