cpu_x86: Move and rename x86ModelHasSignature

Later in this series the function will work on a newly introduced
virCPUx86Signatures structure. Let's move it to the place were all
related functions will be added and rename the function as
virCPUx86SignaturesMatch for easier review of the virCPUx86Signatures
patch.
