Add support to define structures in mig.v1.8+git20221111

Basic syntax is presented below and allows users to define
nested structured types by using simpler or structure types as
members. Mig will use the C padding and alignment rules to produce
the same size as the corresponding C structures.

type timespec_t = struct {
  uint32_t tv_sec;
  uint32_t tv_nsec;
};

This allows us to build stubs that are more easily adaptable to other
architectures.
