gary rong 028af3457d cmd/utils: fix command line flag resolve (#20167)
In Geth, we have two sources for configuration:
(1) Config file
(2) Command line flag

Basically geth will first resolve config file and then overwrite
configs with command line flags.

This issue is: geth should only overwrite configs if flags are truly
set. So before we apply any flag to configs, `GlobalIsSet` check
is necessary.
