Drm hwcomposer project has some code-style inconsistencies. This is the initial step to unify code-style of the code. Clang-tidy is a great tool which can not only suggest correct styling, but also allow predicting the errors in the code and suggest correct coding approaches to avoid potential weaknesses. CI was tuned to check clang-tidy recommendation for some part of the code which is ready ATM (can be built outside AOSP tree). For this part a limited set of clang-tidy checks has applied (coarse check). Header files aren't checked at all. Starting from now new code files must be included into the list that is checked by almost all clang-tidy checks (fine checklist). New header files should be also included into this list. See '.gitlab-ci-clang-tidy-fine.sh'. Signed-off-by: Roman Stratiienko <r.stratiienko@gmail.com>
