KVM: arm/arm64: Extend arch CAP checks to allow per-VM capabilities
KVM capabilities can be a per-VM property, though ARM/ARM64 currently does not pass on the VM pointer to the architecture specific capability handlers. Add a "struct kvm*" parameter to those function to later allow proper per-VM capability reporting.
