This adds sections for KVM API extension for pointer authentication. A brief description about usage of pointer authentication for KVM guests is added in the arm64 documentations.

It's also worth mentioning that CONFIG_ARM64_VHE=y is required for guest support.
Is it worth making this dependency explicit in Kconfig? For SVE, I have config ARM64_SVE depends on !KVM || ARM64_VHE to implement this.
