Simplify CDP Mode imports when using the pure CDP formats

Currently, some examples are using this:

from seleniumbase.core import sb_cdp
from seleniumbase.undetected import cdp_driver

By editing an __init__.py file, that can be simplified to this:

from seleniumbase import sb_cdp
from seleniumbase import cdp_driver

That's easier to remember, and looks cleaner too.

There's probably a lot more that I can simplify along with this.

More simplifications are coming as part of #3571.
