view: decouple always-on-top windows from the omnipresent state

Before this commit, always-on-{top,bottom} windows were always visible
on all workspaces (omnipresent) because the they were not in
per-workspace trees like normal windows.

This commit fixes this by introducing per-layer trees in
`struct workspace`.

I also added `enum view_layer` and `view->layer` for simplicity.
