Khang Nguyen Duy 993a83081a std.fmt: fix unecessary deref on user-defined format function ...

When formatting a pointer to user type, currently it needs to be
dereferenced first, then call `formatType` on the child type.

Fix the problem by checking for "format" function on not only the type
itself, but also the struct it points to. Add hasMethod to std.meta.
