target/i386: KVM: allow fast string operations if host supports them

These are just a flag that documents the performance characteristic of
an instruction; it needs no hypervisor support.  So include them even
if KVM does not show them.  In particular, FZRM/FSRS/FSRC have only
been added very recently, but they are available on Sapphire Rapids
processors.
