target/i386: kvm: add support for TSC scaling
Linux 5.14 will add support for nested TSC scaling.  Add the
corresponding feature in QEMU; to keep support for existing kernels,
do not add it to any processor yet.

The handling of the VMCS enumeration MSR is ugly; once we have more than
one case, we may want to add a table to check VMX features against.
