CODEOWNERS: Expand scope

Improve the `CODEOWNERS` file by specifying more groups.

Since GitHub automatically checks the `CODEOWNERS` file when a PR is
created and adds all matching groups as reviewers for the PR, this may
help reduce the PR backlog since the right people will be alerted and
requested to review the PR. That should improve the quality of reviews
(and thus the quality of the landed code). It may also have a positive
effect on PR velocity.

> **Note:**
>
> This PR combines the other `CODEOWNERS` files so we have
> a single, visible, top-level file.

See: kata-containers/community#253

Fixes: kata-containers#3804.
