feat(wm): add native window maximization toggle

Windows that have been maximized do not retain their maximized state
across workspaces as workspaces are built on top of sending SW_HIDE and
SW_SHOW events which at various points of the event loop end up
overriding SW_SHOWMAXIMIZED and SW_SHOWMAXIMIZE.

To handle this use case, I have added a new 'komorebic toggle-maximize'
command which sends SW_MAXIMIZE for a window and keeps a record of the
window in the focused workspace in the same way that monocle windows are
tracked.

In this way, komorebi can know when switching to a workspace if it has
to restore a window to a native maximized state.

Some additional edge cases are caught in this commit in showing and
hiding workspaces, to also account for floating windows and monocle
containers.
