Test of apache/datafusion#6937
This is a test PR to see what effect adding extra inlining encouragement and unsafe access can get DataFusion's aggregation
This is inspired by @yahoNanJing 's work here: #4524
I would like to know how much of the performance boost is due to the raw table's unsafe APIs vs how much is due to the data layout
