Define naming rules for iceoryx and check them with `clang-tidy`

## Brief feature description

Currently iceoryx has somehow inconsistent naming rules and naming conventions which are not verified by `clang-tidy`.

### rules which deviate from the iceoryx naming guidelines

In `iceoryx_binding_c`
* snake_case is used for function names
* every function has an `iox_` prefix and an additional prefix which names the corresponding c++ class and is named after the method it calls
* lowerCamelCase for variable names
* enums have an `iox_` prefix
* enum values have the enums name without the `iox_` has prefix, but not consistently, see `log.h`

In `iceoryx_hoofs/cxx`
* classes, methods and functions follow a mixture of snake_case and UpperCamelCase and lowerCamelCase

## Detailed information

The following approaches are possible:
* define the naming rules in separate `.clang-tidy` files which inherit from the main `.clang-tidy` file and are stored in the folders with the deviation.
* Unify the naming rules. Here we can distinct between languages and have a unified naming rule for C++ and exclude binding c from it.

A unified naming rule would make as more incompatible (but not less understandable) from the STL and would introduce a lot of API breaking changes. Multiple naming rules may look inconsistent and are maybe harder to maintain.

Start by reviewing the existing .clang-tidy configuration and the naming patterns in iceoryx_binding_c and iceoryx_hoofs/cxx, including the enum cases in log.h. Clarify whether separate configurations or unified rules are wanted, then define the selected conventions and verify that clang-tidy checks the relevant code without unintended API changes.
