[PATCH] D35257: [clang-tidy] Add new modernize use unary assert check

The check finds `static_assert` declarations with empty messages, and
 replaces them with an unary `static_assert` declaration.

The check is only applicable for C++17 code.

The following code:

  void f_textless(int a){
    static_assert(sizeof(a) <= 10, "");
  }
   

is replaced by:

  void f_textless(int a){
    static_assert(sizeof(a) <= 10 );
  }
