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

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

Also consider can we define a (per project) setting around these parameters if the user is overusing layers or has too big amount of vertices in their mesh etc.?
