Is your feature request related to a problem? Please describe the problem.

To support the new client generation, we need a new Kiota Core package. That needs to happen for every language.

Client library/SDK language

None

Describe the solution you'd like

We need a package that references all the Kiota packages so we can rely on a single package instead of all the packages + serialization. We also need a derived request adapter to auto-register the serialization pieces.
