Disable debug preemption in x86_64 (#11792)
Performance improvement. In 6.1, the recommended default for DEBUG_PREEMPT was y. However, this led to performance hits and overhead due to frequent calls to __this_cpu_preempt_check(). The default was later changed in "[cc60039] lib/Kconfig.debug: do not enable DEBUG_PREEMPT by default". Therefore, go with new recommeded default to improve performance.
