  -----------
  [clang-tidy] Fix modernize-use-std-print check when return value used

The initial implementation of the modernize-use-std-print check was
capable of converting calls to printf (etc.) which used the return value
to calls to std::print which has no return value, thus breaking the
code.

Use code inspired by the implementation of bugprone-unused-return-value
check to ignore cases where the return value is used. Add appropriate
lit test cases and documentation.
