x86 hvm mce: Support HVM Guest virtual MCA handling.
When MCE# happens, if the error has been contained/recovered by XEN
and it impacts one guest Domain(DOM0/HVM Guest/PV Guest), we will
inject the corresponding vMCE# into the impacted Domain. Guest OS will
go on its own recovery job if it has MCA handler.
