x86/vmce, tools/libxl: expose LMCE capability in guest MSR_IA32_MCG_CAP

If LMCE is supported by host and ' mca_caps = [ "lmce" ] ' is present
in xl config, the LMCE capability will be exposed in guest MSR_IA32_MCG_CAP.
By default, LMCE is not exposed to guest so as to keep the backwards migration
compatibility.
