Some curve modifiers (namely Hook, SoftBody and MeshDeform) can only work on pre-tesselated spline points. Before the modifier UI refactor in rB9b099c86123f, users would get the 'Apply on Spline' option, but disabled and with a tip explaining why this cant be changed. After rB9b099c86123f though, this button was always enabled [but disfunctional] leaving the user without an explanation why this has no effect. Now restore this functionality since it is quite important information. Additionally, this button now appears to be ON in these cases which makes more sense from the user perspective (so it does not represent the actual setting on the modifier -- this would internally be switched ON in the modifier calculation anyways though, see 'curve_get_tessellate_point') Differential Revision: https://developer.blender.org/D11029
