tools/include: Sync uapi/linux/perf.h with the kernel sources

To pick up changes from:

  608f697 perf/x86/intel: Support new data source for Lunar Lake

This should be used to beautify perf syscall arguments and it addresses
these tools/perf build warnings:

  Warning: Kernel ABI header differences:
  diff -u tools/include/uapi/linux/perf_event.h include/uapi/linux/perf_event.h

Please see tools/include/uapi/README for details (it's in the first patch
of this series).
