perf intel pt: Update instruction decoder for APX and other new instructions

Hi

The x86 instruction decoder is used not only for decoding kernel instructions. It is also used by perf uprobes (user space probes) and by perf tools Intel Processor Trace decoding. Consequently, it needs to support instructions executed by user space also.

It should be noted that there are 2 copies of the instruction decoder. One for the kernel and one for tools, which is a policy to prevent changes from breaking builds.

Changes are based upon documents:

Intel® Advanced Performance Extensions (Intel® APX) Architecture Specification
April, 2024 Revision 4.0 355828-004

Intel® Architecture Instruction Set Extensions and Future Features Programming Reference March 2024 319433-052

The patches depend on a patch by Chang S. Bae that they have already submitted in their Key Locker patch set. Nevertheless, the patch is included in this patch set as well.

The final patch is an update to the perf tools' "x86 instruction decoder test - new instructions" test, which provides testing.
