nohz: ensure users are aware boot CPU is not NO_HZ_FULL
This bit of information is in the Kconfig help text:
"Note the boot CPU will still be kept outside the range to
handle the timekeeping duty."
However neither the variable NO_HZ_FULL_ALL, or the prompt
convey this important detail, so lets add it to the prompt
to make it more explicitly obvious to the average user.
