executor: sys/linux: SYZOS: add AMD VMLOAD and VMSAVE primitives
This patch introduces SYZOS_API_NESTED_AMD_VMLOAD and
SYZOS_API_NESTED_AMD_VMSAVE.
These primitives allow the L1 guest to execute the VMLOAD and VMSAVE
instructions, which load/store additional guest state (FS, GS, TR, LDTR,
etc.) to/from the VMCB specified by the 'vm_id' argument.
This stresses the KVM L0 instruction emulator, which must validate the
L1-provided physical address in RAX and perform the state transfer.
