disabled some clang-tidy checks which are not necessary and slow down the analysis / documented disabled checks - #4468

We might be able to disable the extremely expensive misc-confusable-identifiers check as well since it is covered by the -Wbidi-chars GCC compiler warning which is enabled by default - see https://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html. So the additional static analysis might not be necessary at all.
