macosx: Make collection view layouts consistent, unify setup

At the moment, collection view layouts are generally inconsistent in terms of item sizing, insets, and inter-item spacing. They are also set up in different ways which makes the effect of changes difficult to predict.

This MR adds consistency to the layouts and unifies setup to occur in VLCLibraryWindow.m.
