MINOR: [Docs][C++] Improve Input Shapes section of Compute doc

[js8544]

1. The function that only takes arrays should be array_sort_indices, not sort_indices.
2. IMO The word either implies that array_sort_indices also accepts chunked arrays but in fact it doesn't. So I changed either to particular input types.
3. There are no mention of two dimensional data types, i.e. RecordBatch and Table, throughout the Input Shapes section, which I feel like is a miss. So I added sort_indices as an example for them.

['Python', 'R'] benchmarks have high level of regressions.
