This change adds common kvm specific support to handle KVM VM file descriptor change. KVM VM file descriptor can change as a part of confidential guest reset mechanism. A new function api kvm_arch_on_vmfd_change() per architecture platform is added in order to implement architecture specific changes required to support it. A subsequent patch will add x86 specific implementation for kvm_arch_on_vmfd_change() as currently only x86 supports confidential guest reset.
