ARROW-1846: [C++][Compute] Implement "any" reduction kernel for boolean data

As discussed on Jira this is a short-circuiting Max for booleans implemented on top of the existing `min_max` kernel.

As is there are no options: null is always taken to evaluate to false.

If we want to include control over null handling I can either add `Options` to the kernel or I can implement an `any_kleene` kernel by analogy with the `and_kleene` and `or_kleene` logical kernels that we have.

In Python the two options would look like:

``` python
In []: a = pa.array([True, None], type='bool')
    ...:
    ...: # option 1
    ...: pc.any(a).as_py() is True
    ...: pc.any_kleene(a).as_py() is None
    ...:
    ...: # option 2
    ...: pc.any(null_handling='skip') is True
    ...: pc.any(null_handling='emit_null') is None
```

Closes #8294 from arw2019/ARROW-1846
