x86/insn: Add VEX versions of VPDPBUSD, VPDPBUSDS, VPDPWSSD and VPDPWSSDS

x86/insn: Add VEX versions of VPDPBUSD, VPDPBUSDS, VPDPWSSD and VPDPWSSDS

[ Upstream commit b8000264348979b60dbe479255570a40e1b3a097 ]

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.

Intel Architecture Instruction Set Extensions and Future Features manual
number 319433-044 of May 2021, documented VEX versions of instructions
VPDPBUSD, VPDPBUSDS, VPDPWSSD and VPDPWSSDS, but the opcode map has them
listed as EVEX only.

Remove EVEX-only (ev) annotation from instructions VPDPBUSD, VPDPBUSDS,
VPDPWSSD and VPDPWSSDS, which allows them to be decoded with either a VEX
or EVEX prefix.
