hw/arm/virt: KVM: Enable PAuth when supported by the host
Add basic support for Pointer Authentication when running a KVM
guest and that the host supports it, loosely based on the SVE
support.
Although the feature is enabled by default when the host advertises
it, it is possible to disable it by setting the 'pauth=off' CPU
property. The 'pauth' comment is removed from cpu-features.rst,
as it is now common to both TCG and KVM.
Tested on an Apple M1 running 5.16-rc6.
