Layers panel: Reset to Initial Visibility

Layer options in the Layers panel header resets every layer to the state the
file's default configuration (/OCProperties /D) gives it, as Acrobat does.
Visibility is view state, so the reset doesn't mark the document changed and
doesn't enter Undo. doc_info now reports each layer's initial state.
