Make host_state a property of a loaded_vmcs so that it can be used as a cache of the VMCS fields, e.g. to lazily VMWRITE the corresponding VMCS field. Treating host_state as a cache does not work if it's not VMCS specific as the cache would become incoherent when switching between vmcs01 and vmcs02. Move vmcs_host_cr3 and vmcs_host_cr4 into host_state. Explicitly zero out host_state when allocating a new VMCS for a loaded_vmcs. Unlike the pre-existing vmcs_host_cr{3,4} usage, the segment information is not guaranteed to be (re)initialized when running a new nested VMCS, e.g. HOST_FS_BASE is not written in vmx_set_constant_host_state().
