scripts/perf: Add tool for collecting cpu load

As we are at it, remove bottleneck in get_cpu_time() - avoid reading
/proc/stat line by line to find target cpu as in case of systems with
hundreds of cpus this increases the get_cpu_time()'s runtime quite
significantly. Instead, slurp all cpu stats with a single read and
expose them as _cpuN[].

On a system with 144 cpus single get_cpu_time()'s iteration dropped
from ~5s to ~1s.

Note that this tool uses plain integer arithmetic so the results per
cpu time may be a bit off due to lacking precision. Nevertheless,
they should serve nicely as an approximation.
