Hello, please review this small  fix .

At the moment,  the test    jdk/jfr/event/os/TestCPUInformation.java   fails on AArch64 with the following error :

java.lang.RuntimeException: Value not in (Intel, AMD, Unknown x86, SPARC, ARM, PPC, PowerPC, AArch64, zArch), field='description', value='0x50:0x0:0x000:1, simd'

Reason is that  the  jdk.CPUInformation   event misses  a known CPU identifier value  in the  description,  see the  description part of it  :

Event: jdk.CPUInformation {
  description = "0x50:0x0:0x000:1, simd"
  sockets = 8

The patch adds  the CPU identifier info to  the   _cpu_desc   string  where it is taken from   .
Please compare also with the ppc - implementation where the info  (PPC)   is already added .


50     snprintf(_cpu_desc, CPU_DETAILED_DESC_BUF_SIZE, "PPC %s", features_string());

Bug/webrev :



Thanks, Matthias
