Subject: Remove non-Tungsten mode in Spark 3?

The issue with the offheap mode is it is a pretty big behavior change and does require additional setup (also for users that run with UDFs that allocate a lot of heap memory, it might not be as good).

I can see us removing the legacy mode since it's been legacy for a long time and perhaps very few users need it. How much code does it remove though?
