[vm tool] Introduce check-feature-enabled
Introduce this command to allow host to query feature (such as
com.android.kvm.LLPVM_CHANGES) is enabled on device. Implement this in
libavf_features, so that virtmrg can share code.
Bug: 325630143
Test: Inspect output of vm check-feature-enabled
com.android.kvm.LLPVM_CHANGES
