Broken: 3.1.0
Worked: 3.0.1

Apparently caused by 44b0c70919

Short description of error
Transferring face corner data using bpy.ops.object.data_transfer() crashes Blender on the Nearest Corner and Best Matching Normal mapping setting.
crash_face_corner_transfer-2022-04-04_16.27.15.mp4

Exact steps for others to reproduce the error
From default startup scene:

Duplicate default cube
Select both cubes
Run Data Transfer operator (e.g. using {key Ctrl L})
Select a face corner data layer for transfer (e.g. UV Maps)
Select the Nearest Corner and Best Matching Normal for face corner mapping

The problem is the code in mesh_calc_modifiers that makes instancing of unmodified mesh work. It skips computing final normals when runtime->mesh_eval != NULL, assuming that another instance has already done so.

However in this case, we are re-evaluating the modifier stack for an operator, since the datamask does not match what we had computed for viewport display.

I guess it's a longer term thing, but I'd like to do the same refactor for derived face corner normals that I did for face and vertex normals, i.e. calculate them lazily, which should solve issues like this. So maybe a temporary fix is fine here. (Didn't look into this specific bug deeply).
