Related to #6969

Inspired by the @yahoNanJing 's work in apache/arrow-rs#4524 (comment) I am seeing how much extra performance there is to be gained via inlining and unchecked access in group keys: apache/arrow-rs#4539

I think there is still substantial performance to be had by avoiding the row format entirely for single column groups, but I will explore that theory later
