panfrost: Merge varyings_mem into transient buffers

Theoretically we would like these split since varyings can have
specially optimized flags (no map, coherent local). For now, since
neither of these flags is particularly meaningful right now, merge them
together instead of special casing varyings_mem.

Saves upwards of 64MB of RAM per context.
