Description

Is your feature request related to a problem? Please describe.
While WinForms exposes a lot of COM interfaces, there are many that are only consumed. Currently CCW generation happens for every COM struct.

Describe the solution you'd like
Ideally something like this in the JSON file:

    "comInterop": {
        "generateCCW": [
            "IAccessible"
        ]
    }

Research direction

Start by tracing the existing COM struct CCW generation and the JSON configuration entry point described in the issue. Define the behavior for the proposed comInterop.generateCCW list, then verify that only listed interfaces generate CCWs while existing generation behavior is covered by tests.
