Cleanup: Remove unused mesh dirty flags

These were only set in two places. One was related to "tessellated loop
normal", and the other derived corner normals. The values were never
checked though, after 59343ee1627f4c369. The handling of dirty face
corner normals is clearly problematic, but in the future it should be
handled like the normal layers on the other domains instead.
