In general, public headers should not have compiler-specific constructs but both the core and the port headers have attributes, which are non-standard. It's better to factor out such constructs to a common place (a new header) and hide them behind macros, which can then be defined on a per-compiler basis. This patch moves the existing definitions of function attributes and likely/unlikely builtins to the new header. At the same time, it unifies the names of these attribute defines and where they are used. Moreover, it touches on jerry-main and removes the uses of `__attribute__((unused))` entirely and replaces them with the elsewhere used `(void) ...` pattern.
