Drives attached at boot via the existing CLI options (--image, --extra-drive) must not be detachable at runtime via the upcoming RemoveStorage Varlink method, while drives added at runtime via AddStorage must be. Track this distinction with a new QMP_DRIVE_REMOVABLE property flag — placed alongside QMP_DRIVE_BLOCK_DEVICE, not in the transient BlockDeviceStateFlags state-machine, since "may be removed" is a permanent property of the drive. vmspawn_qmp_remove_block_device() now early-rejects unknown ids with io.systemd.MachineInstance.NoSuchStorage and immutable drives with io.systemd.MachineInstance.StorageImmutable. vmspawn_qmp_add_block_device() loses its 'static' qualifier and gets a declaration in the header, so the runtime hotplug path (vmspawn-bind-volume.c, next) can dispatch into it directly.
