[clang-tidy] implement check for goto

The usage of `goto` is discourage in C++ since forever. This check implements
a warning for every `goto`. Even though there are (rare) valid use cases for
`goto`, better high level constructs should be used.

`goto` is used sometimes in C programs to free resources at the end of 
functions in the case of errors. This pattern is better implemented with
RAII in C++.
