perf tools fixes for v6.0: 1st batch 

- Fix alignment for cpu map masks in event encoding.
 
 - Support reading PERF_FORMAT_LOST, perf tool counterpart for a feature
   that was added in this merge window.
 
 - Sync perf tools copies of kernel headers: socket, msr-index, fscrypt,
   cpufeatures, i915_drm, kvm, vhost, perf_event.
