redhat/configs: Enable CONFIG_RCU_SCALE_TEST & CONFIG_RCU_REF_SCALE_TEST

Waiman Long requested to merge llong1/centos-stream-9:bz2070740_rcutest into main

Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=2070740
Upstream Status: RHEL only
MR: !657 (merged)
Brew: http://brew-task-repos.usersys.redhat.com/repos/scratch/llong/kernel/5.14.0/72.bz2070740_rcutest.el9/
Tested:

After installing the brew kernel rpms,
# rpm -ql kernel-modules-internal-5.14\* | grep /rcu
/lib/modules/5.14.0-72.bz2070740_rcutest.el9.x86_64/internal/kernel/rcu
/lib/modules/5.14.0-72.bz2070740_rcutest.el9.x86_64/internal/kernel/rcu/rcuscale.ko.xz
/lib/modules/5.14.0-72.bz2070740_rcutest.el9.x86_64/internal/kernel/rcu/rcutorture.ko.xz
/lib/modules/5.14.0-72.bz2070740_rcutest.el9.x86_64/internal/kernel/rcu/refscale.ko.xz
So the new RCU test kernel modules are included in
kernel-modules-internal.

The modprobe command was then used to load and unload each of the
test kernel successfully without problem.

Enable CONFIG_RCU_SCALE_TEST and CONFIG_RCU_REF_SCALE_TEST to build the rcuscale and refscale test kernel modules to be included in kernel-modules-internal rpm to be used for internal QE testing.
