Why are these now moved out of the "Flags for Ignition" section?

When writing this CL I got very confused initially because I had no idea
ignition_staging turned on the compiler dispatcher. The compiler_dispatcher (and
validate_asm) have nothing to do with Ignition, but we want to turn them on with
the ignition-staging config, so I want to pull out the staging config so it's
clear all the features this flag turns on, even if they are unrelated to
ignition directly.
