Add an SK_PRINTF_LIKE macro, which declares a function to have printf-like
semantics, allowing gcc and clang to check the format string against the
arguments. Enable its use on SkString (printf, appendf, and prependf). Also
define an SK_SIZE_T_SPECIFIER macro so there's a cross-platform way of
printing a size_t.
