  [Sema] check InitListExpr format strings like {"foo"}

Adds InitListExpr case in format string checks.

e.g.

    int sprintf(char *__restrict, const char * __restrict, ...);

    int foo()
    {
        char data[100];
        constexpr const char* fmt2{"%d"};  // no-warning
        sprintf(data, fmt2, 123);
    }
