executor: sys/linux: implement SYZOS_API_NESTED_INTEL_VMWRITE_MASK
The new command allows mutation of Intel VMCS fields with the help
of vmwrite instruction.
In addition to VM ID and field ID, @nested_intel_vmwrite_mask takes
three 64-bit numbers: the set mask, the unset mask, and the flip mask.
This allows to make bitwise modifications to VMCS without disturbing
the execution too much.
Also add sys/linux/test/amd64-syz_kvm_nested_vmwrite_mask to test the
new command behavior.
