executor: sys/linux: implement SYZOS_API_NESTED_AMD_VMCB_WRITE_MASK
The new command allows mutation of AMD VMCB block with plain 64-bit writes.
In addition to VM ID and VMCB offset, @nested_amd_vmcb_write_mask takes
three 64-bit numbers: the set mask, the unset mask, and the flip mask.
This allows to make bitwise modifications to VMCB without disturbing
the execution too much.
Also add sys/linux/test/amd64-syz_kvm_nested_amd_vmcb_write_mask to test the
new command behavior.
