[C++][Compute] Add remainder and quotient compute::Function

[asfimport]

In addition to divide which returns only the quotient, it'd be useful to have a function which returns both quotient and remainder (these are efficient to compute simultaneously), probably as a struct<quotient: T, remainder: T>.

We have a bit of hackery in R to effect these with the existing compute kernel: https://github.com/apache/arrow/blob/master/r/R/expression.R#L71-L90

Would be great to delete that.

Ian Cook / @ianmcook:
We should also expose quotient and modulo compute functions that would presumably use the same code as this but would return only the quotient or only the remainder (ARROW-12755)
