ANDROID: KVM: arm64: Remove the non-consuming hyp trace interface

Following ML discussion, it seems very much likely the non-consuming
upstream version for hyp tracing ("trace" files) will be delayed.

As we want to stick to upstream as much as possible for the next Android
releases, let's remove this interface, not used by our tools before
anyone relies on it.
