Add geometry nodes caches into the outliner!

Currently there's no real way to know what object, what modifier and what node is baked and what is not.

It becomes cumbersome very fast when you have bunch of scenes and thousands of objects where and to find out why your file is 100gb because some modifier is has baked animation on million of polys. (Obviously exaggeration but could happen very easily with big files).

So it would be very nice to have a "datablock" for each baked cache ^_^
