stddef.h: Use compiler macros for built-in integer types

ptrdiff_t, wchar_t, and wint_t are all integer types built-in to the C
language (as opposed to being library-only types defined in a header).
In the past we had to define these typedefs ourselves because of romcc,
but now that it's gone we should use the GCC-provided macros to select
the types the compiler expects.
