Disable CONFIG_DEBUG_PREEMPT to restore performance

Phil Auld requested to merge prauld/centos-stream-9:bz2030877 into main

Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=2030877
Upstream Status: RHEL only

When we enabled PREEMPT_DYNAMIC we also picked up CONFIG_DEBUG_PREEMPT
which causes noticable performance issues, especially on syscall
microbenchmarks. Only enable DEBUG_PREEMPT in the debug build.
