widl: Output correct code for freeing of conformant-sized and non-conformant strings. 

_StubMsg.pfnFree should be used instead of NdrPointerFree for
conformant-sized strings since the buffer will have been allocated
using NdrAllocate.

Non-conformant strings do not need any freeing since they use a buffer
that is allocated on the stack.
