[UX Design] Expose basic optimisation data from the editor to users

Investigate what basic data we have already in the editor that we are not exposing to the users yet: number of layers, amount of storage used for textures, meshes etc. Come up with a way to show this data to the user in as visual manner as feasible.

Also consider can we define any level of indication around these parameters if the user is overusing layers or has too big amount of vertices in their mesh etc.?
