Is your feature request related to a problem or challenge?

We have recently standardised a scalar abstraction upstream, based around the existing Array abstractions.

The rationale behind this is expanded upon here apache/arrow-rs#4393 (comment)

Describe the solution you'd like

I would like ScalarValue to just be a wrapper around an ArrayRef. This would avoid a huge amount of duplicated and/or boilerplate code, whilst also discouraging implementing non-vectorizable kernels based around ScalarValue.

Describe alternatives you've considered
