Disabling extended sizes classes does not appear to have the savings it does on desktop.

This should help 64-bit devices with <4GB RAM substantially, at reduced hardening.
clark for example only has 2.5GB of usable memory and idles at 1.6GB used.
After this change, idle usage drops to 1.1GB!

What is lost?
- sanity checks and redzoning on all devices
- redzoning reportedly however causes issues on some devices such as the Pixel 3/4 and OnePlus 7
- slub sanization on 3.0, 3.4, 4.4 (except google/wahoo), xiaomi/sm6150, and oneplus/sm7250
Note: all 3.4+ devices still have page sanization
