Clang Tidy: Align and setup first set of rules

As discussed in the sync meeting on 10.11.2022, we need to align on some Clang Tidy checks for our repository. Thus, please provide suggestions and examples here in the ticket. After collecting all inputs, we will proceed by consolidating and come up with a first draft to start with.

@rparisha2 @jdobberstein @mbauerm6f @arauschert Looking forward to your suggestions.
