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

[firewave]

See llvm/llvm-project#57527 (comment) for details on the slowdown from clang-tidy-14 to clang-tidy-15 as well as data on the most expensive checks.

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.
