Fixes #163759
When compiled by \�ot_eager\ with \dynamic=True, \ orch.combinations\ failed with \RuntimeError: Cannot call numel() on tensor with symbolic sizes/strides\ because the C++ implementation used \ umel()\ instead of \sym_numel().
This commit fixes it by using \sym_numel()\ and passing \c10::SymInt\ to the mask generation.
