I'm not sure about the naming here, any suggestions are welcome.

Java calls this getDevTools(), I am not sure what is the idiomatic fit for Python.

to start a devtools session in Java -> devTools.createSession();

This method both gets DevTools (loads the proper version) and creates session, then returns both the loaded devtools module and the established connection. start_devtools is the best possible name I came up with for these 2 operations. We could of course split them into 2 separate methods...

for bidi this should be an implementation detail in the higher level APIs, so not too concerned about it.

A general comment that applies to this whole PR - do we want to have typing properly implemented? I'm not familiar with the Python typing system so I did what was the easiest for me. I can re-iterate and add types if that's preferred.

I would invest in typing for the BiDi implementation. Not much in the CDP one.

Types are already available in CDP, the question is should I add types to the WebSocketConnection class.

I don't think this should be the priority right now. Focus on getting the hard parts implemented, and we can get help from others on the typing later.

User description
Initial implementation of #13975. This provides a low-level API that:
Once this is merged, I'll work on the subsequent PRs that provide high-level API backed by CDP for now (network interception, log events, basic authentication, etc).
The implementation can also be used to send BiDi commands and subscribe to events once BiDi is implemented in Python (assuming we follow the same pattern as for CDP).
