Is your feature request related to a problem or challenge?

Currently there are countless duplicates of the same code around the project:
namely, receive a slice of exprs and an input batch, evaluate each expr with the input batch and call to_array(batch.num_rows) on the resulting ColumnarValues.
Most of these code chunks are inlined within functions, but one of them lives in aggregates/mod.rs, which seems out of place, and more importantly is marked pub.

Describe the solution you'd like

Move this pub function somewhere in datafusion_common, make all other occurrences call this function.
