New clang-format configuration added to determinate code style.
The default version is 16.
Extend CMake to copy config file to build root.
Method/function separator deprecation:
In case if function/method has declaration in header,
definition must not have related comment.
Only //==== [100 chars] ==== is allowed as a not connected
separator.
In case if function/method has NOT declaration in header,
definition must have related comment in doxygen style:
// Descriptions
// @param
// @return
Or just function/method separator:
//==== [100 chars] ====
All old separators with no description must be replaced to
//==== [100 chars] ====
