Enclose `CMAKE_EXTRA_INCLUDE_FILES`, `CMAKE_REQUIRED_DEFINITIONS`, `CMAKE_REQUIRED_FLAGS`, `CMAKE_REQUIRED_INCLUDES`, `CMAKE_REQUIRED_LIBRARIES`, `CMAKE_REQUIRED_LINK_OPTIONS`, settings within `cmake_push_check_state()`/`cmake_pop_check_state()` calls. It prevents spilling them into other feature checks. It also replaces manual resets found in some places (which can have the undesired side-effect of destroying values meant for global use.) Cherry-picked from #15157 Closes #15251
