Hope to add description information to some classes to help debugging

Feature

When debugging some rendering-related code, I always don't know who DrawCommand, Framebuffer, and PassState belong to.

Inspired by #12119, I think we can add a description field to the above classes to help debugging, such as:

The task to open an issue was still on my TODO list (as of a comment in the linked PR). So this is done now 🙂

The PR contains some further details and examples of what such a description may look like, and where it could be useful.

For me, this mainly referred to the DrawCommand (because that was the core part of my task back then). But I could imagine that some other classes could benefit from some sort of description.
