Geometry Node: Finding objects by name and Info about their names.

Now the output of all objects occurs exclusively by specifying in the socket field.

• Objects
• Image
• Materials
• Collections

All these objects have: Name. Like a node Image Info in developer.blender.org/D15042

All of them can be found by name in the project data. Like a node Find Material in developer.blender.org/D15176

Some of them have: Child. For some objects, by Index can get a child. This is partly covered developer.blender.org/D14064 .

That is, theoretically, it is possible to offer a design where there is no need to make large data inputs of different levels. The user for his node group can accept the naming convention and enter only a specific instance.

Problem: Ownership of an object. If for Objects and Collections the possibility of deletion during garbage collection is not so high, then for Images, Materials.

If we refuse to explicitly specify all resources by the user, then the nodes should be able to independently own the resources and prevent them from being deleted.
