Cleanup superfluous `clang-tidy` suppressions

## Brief feature description

In some parts of the code certain `clang-tidy` rules are suppressed which are also deactivated in the `.clang-tidy` file. Those suppression should be removed from the code.

Furthermore, a CI script shall be written which verifies that no new suppression's for rules which are deactived are introduced.
The CI shall fail and block the code when this happens.

Extracted from: #1196

Start by reviewing the repository's .clang-tidy file and locating code suppressions for rules disabled there. Then inspect the existing CI configuration to determine where a verification script belongs. Done means redundant suppressions are removed and CI blocks new suppressions for deactivated rules.
