Rename iterator debugging flag in GN.

Convert from "disable"=true to "enable"=false for clarity.

Add hints to GN build for debugging.

Removed the !is_android check in the iterator debugging. This is redundant with the is_linux check (is_linux used to be set for Android which is why this code got written).
