perf/x86/rapl: Add support for Intel Arrow Lake U

Add Arrow Lake U model for RAPL:

  $ ls -1 /sys/devices/power/events/
  energy-cores
  energy-cores.scale
  energy-cores.unit
  energy-gpu
  energy-gpu.scale
  energy-gpu.unit
  energy-pkg
  energy-pkg.scale
  energy-pkg.unit
  energy-psys
  energy-psys.scale
  energy-psys.unit

The same output as ArrowLake:

  $ perf stat -a -I 1000 --per-socket -e power/energy-pkg/
