[RFC kvm-unit-tests 03/12] lib: x86: Import insn decoder from Linux

[Varad Gautam <varadgautam@xxxxxxxxx>]

Processing #VC exceptions on AMD SEV-ES requires instruction decoding
logic to set up the right GHCB state before exiting to the host.

Pull in the instruction decoder from Linux for this purpose.
