target/i386: Export MSR_ARCH_CAPABILITIES bits to guests
On Intel CPUs there are certain bits in MSR_ARCH_CAPABILITIES that
indicates if the CPU is not affected by a vulnerability. Without these
bits guests may try to deploy the mitigation even if the CPU is not
affected.
Export the bits to guests that indicate immunity to hardware
vulnerabilities.
