x86, apic: Limit apic dumping, introduce new show_lapic= setup option
In case if a system has a large number of cpus printing apics
contents may consume a long time period.
We limit such an output by 1 apic by default. But to have an
ability to see all apics or some part of them we introduce
"show_lapic" setup option which allow us to limit/unlimit the
number of APICs being dumped.
Example: apic=debug show_lapic=5, or apic=debug show_lapic=all
Also move apic_verbosity checking upper that way so helper routines
do not need to inspect it at all.
