Increase visibility of options to open editor/player log

The actions currently live in the gear icon of the Unity tool window, which is a little hard to discover. Perhaps add them to the Unity drop down on the main toolbar? Or as toolbar actions in the Unity tool window? Would it work as new tabs on the Unity toolbar - "Player log" and "Editor log" (but that has implications on loading and reloading the files)

The issue names the Unity tool window gear actions and possible main-toolbar or Unity-toolbar entry points, but no files or tests. Begin by tracing where those log-opening actions are exposed and how toolbar tabs would load or reload the files. Done requires an agreed placement and behavior for opening the Editor and Player logs, including the loading implications.
