tools/x86/kcpuid: Update bitfields to x86-cpuid-db v2.3

Browse Source 
Update kcpuid's CSV file to version 2.3, as generated by x86-cpuid-db.

Summary of the v2.3 changes:

* Per H. Peter Anvin's feedback, leaf 0x3 is not unique to Transmeta as
  the CSV file earlier claimed.  Since leaf 0x3's format differs between
  Intel and Transmeta, and the project does not yet support having the
  same CPUID bitfield with varying interpretations across vendors, leaf
  0x3 is removed for now.  Given that Intel discontinued support for PSN
  from Pentium 4 onward, and Linux force disables it on early boot for
  privacy concerns, this should have minimal impact.

* Leaf 0x80000021: Make bitfield IDs and descriptions coherent with each
  other.  Remove "_support" from bitfield IDs, as no other leaf has such
  convention.
