Some drivers (e.g. Panfrost) don't support packing of varyings when used for transform feedback. This new constant ensures that any varying used for xfb is aligned at the start of a slot and won't be packed with other varyings. Scenarios where transform feedback declarations are related to an array element or a struct member will be handled in a subsequent patch.
