x86/insn: Add some Intel instructions to the opcode map

[ Upstream commit b980be189c9badba50634671e2303e92bf28e35a ]

Add to the opcode map the following instructions:
        cldemote
        tpause
        umonitor
        umwait
        movdiri
        movdir64b
        enqcmd
        enqcmds
        encls
        enclu
        enclv
        pconfig
        wbnoinvd

For information about the instructions, refer Intel SDM May 2019
(325462-070US) and Intel Architecture Instruction Set Extensions
May 2019 (319433-037).

The instruction decoding can be tested using the perf tools'
"x86 instruction decoder - new instructions" test as folllows:
