Introduce new OpenMP 5.0 depend object type.

[AndreyChurbanov]

Summary

The implementation of depobj is actually transparent to runtime library (and to users) and should be done by compiler. But the library needs type declarations in public headers, so that users could declare objects of omp_depend_t type (C/C++) or integers of omp_depend_kind kind (Fortran). That is done by this patch.

LGTM.
