[jira] [Created] (ARROW-12813) [C++] Support for a `full` compute function

Weston Pace created ARROW-12813:
-----------------------------------

             Summary: [C++] Support for a `full` compute function
                 Key: ARROW-12813
                 URL: https://issues.apache.org/jira/browse/ARROW-12813
             Project: Apache Arrow
          Issue Type: Improvement
          Components: C++
            Reporter: Weston Pace


Given a scalar value and a length return an array where all values are equal to the scalar value.

The name "full" is derived from [https://numpy.org/doc/stable/reference/generated/numpy.full.html] but if anyone has a more clever name please recommend it.

There are a number of utility functions in C++ that do this already.  However, exposing this as a compute function would allow R/Python to easily generate arrays.
