On x86-64, when the underlying hypervisor platform is KVM, no instruction emulator is necessary. KVM handles instruction boundaries internally.
This change allows to skip the iced-x86 dependency on KVM, improving build times, prunes the dependency graph and reduces network traffic during the initial build.
For Hyper-V, the emulator is still necessary on x86-64, so nothing changes there.
This PR is my second attempt addressing the changes requested in the (now closed) #5554.
