Solves long-standing issue when dependencies of disabled modifiers are evaluated. Simple test case: no drivers or animation. Manually enabling modifier is expected to bring FPS up, enabling modifier will bring FPS (sine evaluation can not be avoided) F13336690 More complex test case: modifier visibility is driven by an animated property. In am ideal world FPS during property being zero is fast and when property is 1 the FPS is low. F13336691. Differential Revision: https://developer.blender.org/D15625
