Feature #15730: Add map_with_index method

----------------------------------------
I was converting some Ruby code to Crystal on Rosetta Code and came across this Ruby snippet,
```
arry.each_with_index.map{ |x,y| ......}
```
where ``arry`` is an array of integers.
This wouldn't convert directly into Crystal (wouldn't compile).
Looking at their ``enumerables`` methods they have ``map_with_index``, and that works.
```
arry.map_with_index{ |x,y| ......}
```
I don't know how frequently in Ruby this method combination exits, but I suspect it's somewhat common.
I think this method makes a whole lot of logical sense, would optimize the concept, and makes reading code easier.
Anyway, thanks for any consideration.
