Purpose

Fix code review comments:
blender/blender#104712 (comment)
blender/blender#104712 (comment)
blender/blender#104712 (comment)

Technical steps

  1. Made getting object visibility from depsgraph without using custom functionality.
  2. Made instancing creation to be calculated from depsgraph. Moved to to use one InstancerData in BlenderSceneDelegate for whole scene.
  3. Removed unused code.

Note

After this PR some code cleanup would be required + do some optimization in instancing creation. This would be done in separate PR.
