variable.c: Rename rb_st_copy to rb_iv_tbl_copy

This function was created as a variant of st_copy with firing write
barrier.
It should have more explicit name, such as st_copy_with_write_barrier.
But because it is used only for copying iv_tbl, so I rename it to
rb_iv_tbl_copy now.  If we face other use case than iv_tbl, we may want
to rename it to more general name.
