As part of this, we get rid of the v3dv_xxx_descriptor structs to v3dv_descriptor. The main reason is that in order to support several versions, we would need to define them several times. Also, they were somewhat an overkill even before, as their main advantage was getting the offset for each data on the combined case. That functionality is replaced with some new helpers.
