perf tools fixes for v5.14: 1st batch

Browse Source 
- Skip invalid hybrid PMU on hybrid systems when the atom (little) CPUs are offlined.
 
 - Fix 'perf test' problems related to the recently added hybrid (BIG/little) code.
 
 - Split ARM's coresight (hw tracing) decode by aux records to avoid fatal decoding errors.
 
 - Fix add event failure in 'perf probe' when running 32-bit perf in a 64-bit kernel.
 
 - Fix 'perf sched record' failure when CONFIG_SCHEDSTATS is not set.
 
 - Fix memory and refcount leaks detected by ASAn when running 'perf test', should be
   clean of warnings now.
 
 - Remove broken definition of __LITTLE_ENDIAN from tools' linux/kconfig.h, which was
   breaking the build in some systems.
 
 - Cast PTHREAD_STACK_MIN to int as it may turn into 'long sysconf(__SC_THREAD_STACK_MIN_VALUE),
   breaking the build in some systems.
 
 - Fix libperf build error with LIBPFM4=1.
 
 - Sync UAPI files changed by the memfd_secret new syscall.
