Feature #16812: Allow slicing arrays with ArithmeticSequence (#3241)
* Support ArithmeticSequence in Array#slice

* Extract rb_range_component_beg_len

* Use rb_range_values to check Range object

* Fix ary_make_partial_step

* Fix for negative step cases

* range.c: Describe the role of err argument in rb_range_component_beg_len

* Raise a RangeError when an arithmetic sequence refers the outside of an array
