[FEATURE] (type-safe-api) WebSocket API support for Python

[cogwirrel]

Describe the feature

Add support for WebSocket APIs in Python

Use Case

Consistency with remainder of PDK

Proposed Solution

Need to add the following:

• Runtime: operation handler wrappers
• Runtime: @connect/@disconnect handler wrappers
• Runtime: interceptors
• Runtime: server sdk (wrapping API Gateway Management API SDK)
• Infrastructure
• Handler stubs
• @connect/@disconnect handler stubs
• WebSocket client library
• Integration with InfrastructurePyProject

Other Information

The majority of scaffolding is there already for runtime/handlers/infra - the mustache templates for the python-async-xxx projects in packages/type-safe-api/scripts/generators are copy/pasted REST API implementations that need to be modified to work for websockets.

The projen projects (eg generated-python-async-runtime-project.ts) will likely need to be tweaked slightly to add any dependencies required.

The client library will need to be added - follow the same pattern as the TypeScript websocket client library.

Make sure to remove the validation check once implemented:

aws-pdk/packages/type-safe-api/src/project/type-safe-websocket-api-project.ts
